+```
+
+### Right-Aligned Column Validation
+
+The following columns should align on their right edges:
+- **Pkts**: Right edge at position 77
+- **Volume**: Right edge at position 85  
+- **Timing**: Right edge at position 93
+- **Quality**: Right edge at position 101
+
+Example with proper right alignment:
+```
+Pkts Column (6 chars, right-aligned):
+  1452
+  1110
+   114
+   228
+
+Volume Column (8 chars, right-aligned):  
+   1.9MB
+  1.44MB
+   148KB
+   296KB
+
+Timing Column (8 chars, right-aligned):
+  77.8ms
+   102ms
+   990ms
+   493ms
+
+Quality Column (8 chars, right-aligned):
+Enhanced
+   76.4%
+    7.8%
+   15.7%
+```
+
+## Column Specifications
+
+1. **Flow Number**: Positions 1-3 (right-aligned in 2 chars + 1 space)
+2. **Source**: Positions 4-23 (20 characters, left-aligned)
+3. **Proto**: Positions 24-29 (6 characters, left-aligned)
+4. **Destination**: Positions 30-49 (20 characters, left-aligned)
+5. **Extended**: Positions 50-59 (10 characters, left-aligned)
+6. **Frame Type**: Positions 60-71 (12 characters, left-aligned)
+7. **Pkts**: Positions 72-77 (6 characters, right-aligned)
+8. **Volume**: Positions 78-85 (8 characters, right-aligned)
+9. **Timing**: Positions 86-93 (8 characters, right-aligned)
+10. **Quality**: Positions 94-101 (8 characters, right-aligned)
+
+## Sub-Row Alignment
+
+Sub-rows use:
+- Positions 1-3: Empty spaces (matching flow number space)
+- Positions 4-23: Empty (inherits source from main flow)
+- Positions 24-29: Empty (inherits protocol from main flow)  
+- Positions 30-49: Empty (inherits destination from main flow)
+- Positions 50-59: Extended protocol
+- Positions 60-71: Frame type
+- Positions 72-77: Packet count (right-aligned)
+- Positions 78-85: Volume (right-aligned)
+- Positions 86-93: Timing (right-aligned)
+- Positions 94-101: Percentage (right-aligned)
+
+This ensures perfect column alignment between main flow lines and their sub-rows.

 ## Key Improvements

-1. **Transport Protocol Clarity**: Proto column shows TCP, UDP, ICMP, IGMP, OTHER
-2. **Extended Protocol Support**: Separate column for specialized protocols (CH10, PTP, IENA, NTP)
-3. **Frame Type Detail**: Shows the most common frame type for detailed analysis
-4. **Distinct Source/Destination**: Clear separation with IP:port format
-5. **Left-Aligned Text**: Source, destination, and protocol columns for better readability
-6. **Comprehensive Flow Info**: Transport → Extended → Frame type hierarchy
+1. **Hierarchical Flow Display**: Each flow shows a summary line followed by detailed sub-rows
+2. **Transport Protocol Clarity**: Proto column shows TCP, UDP, ICMP, IGMP, OTHER on main flow line
+3. **Extended Protocol/Frame Breakdown**: Sub-rows show each distinct extended protocol and frame type combination
+4. **Detailed Packet Accounting**: Each sub-row shows packet count, volume, timing, and percentage for that specific type
+5. **Visual Hierarchy**: Main flow line in bold, sub-rows indented and dimmed for clarity
+6. **Complete Protocol Analysis**: See exactly what protocols and frame types comprise each flow
+
+## Flow Structure
+
+### Main Flow Line (Bold)
+- Shows flow summary with source, transport protocol, destination
+- Extended column shows "X types" indicating number of protocol/frame combinations
+- Frame Type column shows "Mixed" or "Single" to indicate complexity
+- Metrics show totals for entire flow
+
+### Sub-Rows (Indented, Dimmed)
+- Each sub-row represents a distinct extended protocol + frame type combination
+- Source, Proto, Destination columns are empty (inherited from main flow)
+- Extended column shows specific protocol (CH10, PTP, IENA, etc.)
+- Frame Type shows specific frame type (CH10-Data, PTP-Sync, UDP, etc.)
+- Metrics show counts, volume, timing, and percentage for that specific combination

 ## Column Widths

- Source: 20 characters (left-aligned)  - IP:port format
- Proto: 6 characters (left-aligned)    - Transport protocol (UDP, TCP, etc.)
- Destination: 20 characters (left-aligned) - IP:port format  
- Extended: 10 characters (left-aligned) - Specialized protocol (CH10, PTP, etc.)
- Frame Type: 12 characters (left-aligned) - Most common frame type
+- Source: 20 characters (left-aligned)  - IP:port format (main flow only)
+- Proto: 6 characters (left-aligned)    - Transport protocol (main flow only)
+- Destination: 20 characters (left-aligned) - IP:port format (main flow only)
+- Extended: 10 characters (left-aligned) - Specialized protocol or summary
+- Frame Type: 12 characters (left-aligned) - Specific frame type or summary
 - Pkts: 6 characters (right-aligned)    - Packet count
 - Volume: 8 characters (right-aligned)  - Data volume with units
 - Timing: 8 characters (right-aligned)  - Average inter-arrival time
- Quality: 8 characters (right-aligned) - Quality percentage or status
+- Quality: 8 characters (right-aligned) - Quality/percentage

-This layout provides clear protocol hierarchy from transport layer through specialized protocols to specific frame types.
+This hierarchical layout provides complete protocol breakdown while maintaining clear visual flow structure.

+# Textual API Reference
+
+This directory contains a comprehensive reference for the Textual library API, focusing on the components used in StreamLens.
+
+## Overview
+
+Textual is a TUI (Text User Interface) framework for Python. This reference covers the key APIs we use.
+
+## Quick Links
+
+- [DataTable Widget Reference](./datatable.md) - Complete DataTable API
+- [Events Reference](./events.md) - Event handling and messages
+- [Common Widgets](./widgets.md) - Other widgets used in StreamLens
+- [Styling Guide](./styling.md) - CSS and styling reference
+
+## Core Concepts
+
+### Messages and Events
+
+Textual uses a message-passing system for communication between widgets:
+
+1. **Events** - User interactions (keyboard, mouse)
+2. **Messages** - Widget-to-widget communication
+3. **Handlers** - Methods that respond to events/messages
+
+### Event Handler Naming
+
+Event handlers follow the pattern: `on_<widget_class>_<event_name>`
+
+Example:
+```python
+def on_data_table_row_selected(self, event: DataTable.RowSelected):
+    # Handle row selection
+```
+
+### Common Pitfalls
+
+1. **RowKey Type**: DataTable row keys are not strings by default
+2. **Event Names**: Check exact event class names (e.g., `RowHighlighted` not `CursorMoved`)
+3. **Method Availability**: Not all expected methods exist (e.g., no `set_row_style()`)
+
+## API Validation
+
+Always validate API usage before implementation:
+
+```python
+# Check available events
+from textual.widgets import DataTable
+print([attr for attr in dir(DataTable) if 'Selected' in attr or 'Highlighted' in attr])
+
+# Check specific method
+print(hasattr(DataTable, 'method_name'))
+```

+# DataTable Widget API Reference
+
+## Overview
+
+The DataTable widget displays tabular data with support for selection, scrolling, and styling.
+
+## Import
+
+```python
+from textual.widgets import DataTable
+```
+
+## Class Hierarchy
+
+```
+Widget → ScrollView → DataTable
+```
+
+## Constructor
+
+```python
+DataTable(
+    *,
+    show_header: bool = True,
+    fixed_rows: int = 0,
+    fixed_columns: int = 0,
+    zebra_stripes: bool = False,
+    header_height: int = 1,
+    show_cursor: bool = True,
+    cursor_foreground_priority: Literal["renderable", "css"] = "renderable",
+    cursor_background_priority: Literal["renderable", "css"] = "renderable",
+    cursor_type: CursorType = "cell",
+    cell_padding: int = 1,
+    name: str | None = None,
+    id: str | None = None,
+    classes: str | None = None,
+    disabled: bool = False
+)
+```
+
+## Key Properties
+
+### Cursor Properties
+- `cursor_row: int` - Current cursor row (0-based)
+- `cursor_column: int` - Current cursor column (0-based)
+- `cursor_coordinate: Coordinate` - (row, column) tuple
+
+### Table Properties
+- `rows: Mapping[RowKey, Row]` - Dictionary of rows
+- `columns: list[Column]` - List of columns
+- `row_count: int` - Number of rows
+- `column_count: int` - Number of columns
+
+## Methods
+
+### Adding Data
+
+```python
+# Add columns
+add_column(label: TextType, *, width: int | None = None, key: str | None = None, default: CellType | None = None) -> ColumnKey
+
+# Add multiple columns
+add_columns(*labels: TextType) -> list[ColumnKey]
+
+# Add a single row
+add_row(*cells: CellType, height: int | None = 1, key: str | None = None, label: TextType | None = None) -> RowKey
+
+# Add multiple rows
+add_rows(rows: Iterable[Iterable[CellType]]) -> list[RowKey]
+```
+
+### Modifying Data
+
+```python
+# Update a cell
+update_cell(row_key: RowKey, column_key: ColumnKey, value: CellType, *, update_width: bool = False) -> None
+
+# Update cell at coordinate
+update_cell_at(coordinate: Coordinate, value: CellType, *, update_width: bool = False) -> None
+
+# Remove row
+remove_row(row_key: RowKey) -> None
+
+# Remove column  
+remove_column(column_key: ColumnKey) -> None
+
+# Clear all data
+clear(columns: bool = False) -> Self
+```
+
+### Navigation
+
+```python
+# Move cursor
+move_cursor(row: int | None = None, column: int | None = None, animate: bool = True, scroll: bool = True) -> None
+
+# Scroll to coordinate
+scroll_to(x: float | None = None, y: float | None = None, *, animate: bool = True, speed: float | None = None, duration: float | None = None, ...) -> None
+```
+
+### Sorting
+
+```python
+# Sort by column(s)
+sort(*columns: ColumnKey | str, reverse: bool = False) -> Self
+
+# Sort with custom key
+sort(key: Callable[[Any], Any], *, reverse: bool = False) -> Self
+```
+
+## Events
+
+### Selection Events
+
+```python
+class RowSelected(Message):
+    """Posted when a row is selected (Enter key)."""
+    row_key: RowKey
+    row_index: int
+
+class CellSelected(Message):
+    """Posted when a cell is selected."""
+    coordinate: Coordinate
+    cell_key: CellKey
+
+class RowHighlighted(Message):
+    """Posted when cursor highlights a row."""
+    row_key: RowKey
+    row_index: int
+
+class CellHighlighted(Message):
+    """Posted when cursor highlights a cell."""
+    coordinate: Coordinate
+    cell_key: CellKey
+
+class ColumnHighlighted(Message):
+    """Posted when cursor highlights a column."""
+    column_key: ColumnKey
+    column_index: int
+```
+
+### Header Events
+
+```python
+class HeaderSelected(Message):
+    """Posted when a column header is clicked."""
+    column_key: ColumnKey
+    column_index: int
+    label: Text
+
+class RowLabelSelected(Message):
+    """Posted when a row label is clicked."""
+    row_key: RowKey
+    row_index: int
+    label: Text
+```
+
+## Common Patterns
+
+### Creating a DataTable
+
+```python
+class MyWidget(Widget):
+    def compose(self) -> ComposeResult:
+        yield DataTable(id="my-table")
+    
+    def on_mount(self) -> None:
+        table = self.query_one("#my-table", DataTable)
+        table.add_columns("Name", "Value", "Status")
+        table.add_row("Item 1", "100", "Active", key="item_1")
+```
+
+### Handling Selection
+
+```python
+def on_data_table_row_highlighted(self, event: DataTable.RowHighlighted) -> None:
+    # React to cursor movement
+    self.selected_row = event.row_key
+
+def on_data_table_row_selected(self, event: DataTable.RowSelected) -> None:
+    # React to Enter key press
+    self.process_selection(event.row_key)
+```
+
+### Preserving Cursor Position
+
+```python
+def refresh_table(self):
+    table = self.query_one(DataTable)
+    
+    # Save position
+    cursor_row = table.cursor_row
+    selected_key = list(table.rows.keys())[cursor_row] if table.rows else None
+    
+    # Update data
+    table.clear()
+    # ... add new data ...
+    
+    # Restore position
+    if selected_key and selected_key in table.rows:
+        row_index = list(table.rows.keys()).index(selected_key)
+        table.move_cursor(row=row_index, animate=False)
+```
+
+## Styling
+
+DataTable supports CSS styling but does NOT have:
+- `set_row_style()` method
+- `set_cell_style()` method
+
+Use CSS classes and selectors instead:
+
+```css
+DataTable > .datatable--cursor {
+    background: $primary 30%;
+}
+
+DataTable > .datatable--header {
+    text-style: bold;
+}
+```
+
+## Type Hints
+
+```python
+from textual.widgets.data_table import RowKey, ColumnKey, CellKey
+from textual.coordinate import Coordinate
+
+# RowKey and ColumnKey are not strings - convert with str() if needed
+row_key_str = str(row_key)
+```
+
+## Common Errors and Solutions
+
+1. **TypeError: 'RowKey' is not iterable**
+   - Solution: Convert to string first: `str(row_key)`
+
+2. **AttributeError: 'DataTable' has no attribute 'set_row_style'**
+   - Solution: Use CSS styling instead
+
+3. **Event not firing**
+   - Check handler name: `on_data_table_row_highlighted` not `on_data_table_cursor_moved`

+# Textual Events and Messages Reference
+
+## Overview
+
+Textual uses an event-driven architecture with two main types of communication:
+1. **Events** - User interactions (keyboard, mouse)
+2. **Messages** - Widget-to-widget communication
+
+## Event Handler Patterns
+
+### Basic Pattern
+
+```python
+def on_<namespace>_<event_name>(self, event: EventType) -> None:
+    """Handle event"""
+```
+
+### Examples
+
+```python
+# Widget events
+def on_button_pressed(self, event: Button.Pressed) -> None:
+    pass
+
+# DataTable events
+def on_data_table_row_selected(self, event: DataTable.RowSelected) -> None:
+    pass
+
+# Key events
+def on_key(self, event: events.Key) -> None:
+    if event.key == "escape":
+        self.exit()
+```
+
+## Common Widget Events
+
+### DataTable Events
+
+| Event | Handler | Description |
+|-------|---------|-------------|
+| `RowHighlighted` | `on_data_table_row_highlighted` | Cursor moves to row |
+| `RowSelected` | `on_data_table_row_selected` | Row selected (Enter) |
+| `CellHighlighted` | `on_data_table_cell_highlighted` | Cursor moves to cell |
+| `CellSelected` | `on_data_table_cell_selected` | Cell selected |
+| `ColumnHighlighted` | `on_data_table_column_highlighted` | Column highlighted |
+| `HeaderSelected` | `on_data_table_header_selected` | Header clicked |
+
+### Button Events
+
+| Event | Handler | Description |
+|-------|---------|-------------|
+| `Pressed` | `on_button_pressed` | Button clicked/activated |
+
+### Input Events
+
+| Event | Handler | Description |
+|-------|---------|-------------|
+| `Changed` | `on_input_changed` | Text changed |
+| `Submitted` | `on_input_submitted` | Enter pressed |
+
+## Custom Messages
+
+### Creating a Custom Message
+
+```python
+from textual.message import Message
+
+class MyWidget(Widget):
+    class DataUpdated(Message):
+        """Custom message when data updates"""
+        def __init__(self, data: dict) -> None:
+            self.data = data
+            super().__init__()
+    
+    def update_data(self, new_data: dict) -> None:
+        # Post custom message
+        self.post_message(self.DataUpdated(new_data))
+```
+
+### Handling Custom Messages
+
+```python
+class MyApp(App):
+    def on_my_widget_data_updated(self, event: MyWidget.DataUpdated) -> None:
+        """Handle custom message"""
+        self.process_data(event.data)
+```
+
+## Event Properties
+
+### Common Event Attributes
+
+```python
+# All events have:
+event.stop()  # Stop propagation
+event.prevent_default()  # Prevent default behavior
+
+# Keyboard events
+event.key  # Key name ("a", "ctrl+c", "escape")
+event.character  # Unicode character
+event.aliases  # List of key aliases
+
+# Mouse events  
+event.x, event.y  # Coordinates
+event.button  # Mouse button number
+event.shift, event.ctrl, event.alt  # Modifier keys
+
+# DataTable events
+event.row_key  # Row identifier
+event.row_index  # Row number
+event.coordinate  # (row, column) tuple
+```
+

+1. **Capture Phase**: Event travels down from App to target
+2. **Bubble Phase**: Event travels up from target to App
+
+```python
+# Stop event propagation
+def on_key(self, event: events.Key) -> None:
+    if event.key == "q":
+        event.stop()  # Don't let parent widgets see this
+```
+
+## Message Posting
+
+### Post to Self
+
+```python
+self.post_message(MyMessage())
+```
+
+### Post to Parent
+
+```python
+self.post_message_no_wait(MyMessage())  # Don't wait for processing
+```
+
+### Post to Specific Widget
+
+```python
+target_widget.post_message(MyMessage())
+```
+
+## Event Debugging
+
+### Log All Events
+
+```python
+def on_event(self, event: events.Event) -> None:
+    """Log all events for debugging"""
+    self.log(f"Event: {event.__class__.__name__}")
+```
+
+### Check Handler Names
+
+```python
+# List all event handlers
+handlers = [m for m in dir(self) if m.startswith('on_')]
+```
+
+## Common Patterns
+
+### Debouncing Events
+
+```python
+from textual.timer import Timer
+
+class MyWidget(Widget):
+    def __init__(self):
+        self._update_timer: Timer | None = None
+    
+    def on_input_changed(self, event: Input.Changed) -> None:
+        # Cancel previous timer
+        if self._update_timer:
+            self._update_timer.cancel()
+        
+        # Set new timer
+        self._update_timer = self.set_timer(0.3, self.perform_update)
+```
+
+### Event Validation
+
+```python
+def on_data_table_row_highlighted(self, event: DataTable.RowHighlighted) -> None:
+    # Validate event data
+    if not event.row_key:
+        return
+    
+    # Convert types if needed
+    row_key_str = str(event.row_key)
+```
+
+## Common Mistakes
+
+1. **Wrong handler name**: `on_data_table_cursor_moved` ❌ → `on_data_table_row_highlighted` ✅
+2. **Missing namespace**: `on_row_selected` ❌ → `on_data_table_row_selected` ✅
+3. **Wrong event class**: `DataTable.CursorMoved` ❌ → `DataTable.RowHighlighted` ✅
+4. **Not converting types**: Assuming `row_key` is string when it's `RowKey` type

+# Maximum Width Dynamic Layout
+
+## Overview
+
+The Flow Analysis View now dynamically adjusts to use the maximum available terminal width, ensuring optimal use of screen real estate regardless of terminal size.
+
+## Dynamic Width Calculation
+
+### Available Space Calculation
+```python
+available_width = terminal_width - 16  # 4 chars left + 4 chars right + 8 safety margin
+```
+
+**Prevents Line Wrapping**: Very conservative calculation ensures content never exceeds terminal width, even on narrow terminals
+
+### Minimum Column Requirements
+| Column | Min Width | Purpose |
+|--------|-----------|---------|
+| Flow # | 3 chars | Flow number with space |
+| Source | 15 chars | Compact IP:port |
+| Proto | 4 chars | Transport protocol |
+| Destination | 15 chars | Compact IP:port |
+| Extended | 6 chars | Extended protocol |
+| Frame Type | 8 chars | Frame type name |
+| Pkts | 6 chars | Right-aligned numbers |
+| Volume | 8 chars | Right-aligned with units |
+| Timing | 8 chars | Right-aligned with units |
+| Quality | 8 chars | Right-aligned percentages |
+
+**Total Minimum**: 81 characters
+
+### Space Distribution Algorithm
+
+1. **Check Available Space**: If terminal width > minimum requirements
+2. **Calculate Extra Space**: `extra = available_width - minimum_total`
+3. **Distribute to Text Columns**: Extra space goes to expandable columns:
+   - Source (IP:port endpoints)
+   - Destination (IP:port endpoints)
+   - Extended (protocol names)
+   - Frame Type (frame type names)
+
+4. **Equal Distribution**: `extra_per_column = extra_space ÷ 4`
+5. **Remainder Handling**: Any leftover space goes to Source and Destination columns
+
+### Example Width Distributions
+
+#### Small Terminal (120 chars)
+```
+Available: 112 chars (120 - 8 margin)
+Extra: 6 chars (112 - 106 minimum)
+Distribution: +1 to Source, +1 to Destination, +1 to Extended, +1 to Frame Type, +2 remainder to Source/Dest
+```
+
+#### Medium Terminal (150 chars) 
+```
+Available: 142 chars (150 - 8 margin)
+Extra: 36 chars (142 - 106 minimum)
+Distribution: +9 to each expandable column
+```
+
+#### Large Terminal (200 chars)
+```
+Available: 192 chars (200 - 8 margin)
+Extra: 86 chars (192 - 106 minimum) 
+Distribution: +21 to each expandable column, +2 remainder to Source/Dest
+```
+
+## Adaptive Features
+
+### Intelligent Truncation
+- Source/Destination fields truncate based on their allocated width
+- IP addresses get maximum space before port numbers
+- Ellipsis (…) indicates truncated content
+
+### Perfect Alignment
+- All right-aligned columns maintain perfect edge alignment
+- Sub-row indentation matches main flow number column width
+- Headers automatically adjust to match column widths
+
+### Responsive Layout
+```
+Small Terminal (120 chars):
+  #   Source               Proto  Destination          Extended Frame Type    Pkts    Volume     Timing    Quality
+
+Large Terminal (200 chars):
+   #   Source                          Proto      Destination                     Extended       Frame Type            Pkts      Volume        Timing      Quality
+```
+
+## Benefits
+
+1. **Maximum Information Density**: Uses every available character of terminal width
+2. **Scalable Design**: Works equally well on narrow and wide terminals
+3. **Perfect Alignment**: All columns line up properly regardless of terminal size
+4. **Responsive Text**: Important text fields expand to show more information on wider screens
+5. **Consistent Metrics**: Numeric columns maintain consistent width for easy comparison
+
+## Implementation Details
+
+### Dynamic Column Width Object
+```python
+self.column_widths = {
+    'flow_num': 4,
+    'source': 25,      # Dynamically calculated
+    'proto': 6,
+    'destination': 25, # Dynamically calculated  
+    'extended': 12,    # Dynamically calculated
+    'frame_type': 14,  # Dynamically calculated
+    'pkts': 8,
+    'volume': 10,
+    'timing': 10,
+    'quality': 10
+}
+```
+
+### Formatting Functions
+- `_calculate_column_widths()`: Determines optimal column widths for current terminal
+- `_format_headers()`: Creates header line with dynamic spacing
+- `_format_flow_summary_line()`: Formats main flow lines with dynamic widths
+- `_format_protocol_frame_line()`: Formats sub-rows with matching alignment
+
+The layout now provides optimal readability and information display regardless of terminal size, from compact laptop screens to ultra-wide monitors.

+# Textual API Validation Checklist
+
+## Before Using Textual APIs
+
+### 1. Event Names
+- DataTable events:
+  - ✅ `RowHighlighted` - When cursor moves to a row
+  - ✅ `RowSelected` - When row is selected (Enter key)
+  - ✅ `CellHighlighted` - When cursor moves to a cell
+  - ✅ `CellSelected` - When cell is selected
+  - ✅ `ColumnHighlighted` - When column is highlighted
+  - ✅ `HeaderSelected` - When header is clicked
+  - ❌ `CursorMoved` - Does NOT exist
+  - ❌ `SelectionChanged` - Does NOT exist
+
+### 2. DataTable Methods
+- ✅ `add_row()` - Add a row with optional key
+- ✅ `clear()` - Clear all rows
+- ✅ `move_cursor()` - Move cursor programmatically
+- ❌ `set_row_style()` - Does NOT exist (use CSS classes)
+- ✅ `add_column()` - Add a column
+- ✅ `remove_row()` - Remove a row by key
+
+### 3. Common Attribute Patterns
+- Properties: `cursor_row`, `cursor_column`, `row_count`, `rows`
+- Events: Always check with `dir(Widget)` or test imports
+- Messages: Custom messages need `from textual.message import Message`
+
+### 4. Model Attributes Checklist
+When adding UI that accesses model attributes:
+- [ ] Check if attribute exists in model class
+- [ ] Add missing attributes with appropriate defaults
+- [ ] Consider if attribute should be calculated or stored
+- [ ] Update any related initialization code
+
+### 5. Testing Strategy
+```python
+# Quick validation script
+from textual.widgets import DataTable
+print("Available events:", [attr for attr in dir(DataTable) if 'Selected' in attr or 'Highlighted' in attr])
+```
+
+### 6. Common Pitfalls
+1. **Event naming**: Textual uses specific naming patterns
+2. **Method availability**: Not all expected methods exist
+3. **CSS vs API**: Some styling must be done via CSS
+4. **Message inheritance**: Custom messages need proper base class
+
+## Validation Commands
+
+```bash
+# Check available attributes
+source venv/bin/activate
+python -c "from textual.widgets import DataTable; print(dir(DataTable))"
+
+# Check specific event
+python -c "from textual.widgets import DataTable; print('EventName' in dir(DataTable))"
+
+# Check imports
+python -c "from textual.widgets import WidgetName"
+```
+
+## Model Validation
+
+Before running the app, validate all model attributes are present:
+```bash
+# Run a quick attribute check
+python -c "from analyzer.models.flow_stats import FlowStats, EnhancedAnalysisData; 
+fs = FlowStats('', ''); 
+print('Required attrs:', ['duration', 'first_seen', 'last_seen', 'jitter'])"
+```

+
+# Textual: Declarative actions
+class StreamLensApp(App):
+    BINDINGS = [("1", "show_flows", "Flow Analysis")]
+    
+    def action_show_flows(self):
+        self.query_one(TabbedContent).active = "flows"
+```
+
+### 5. **Styling & Theming**
+```css
+/* streamlens.tcss */
+FlowTable {
+    height: 1fr;
+}
+
+FlowTable .enhanced-flow {
+    background: $success;
+    color: $text;
+}
+
+.metrics-panel {
+    border: solid $primary;

+# TipTop Design Insights for StreamLens Textual UI
+
+## Key Design Patterns from TipTop
+
+### 1. **Multi-Column Layout with Graphs**
+TipTop uses a clean multi-column layout:
+- Left column: System info and CPU details
+- Center column: Real-time graphs (CPU, Memory, Disk, Network)
+- Right column: Process list with live updates
+
+### 2. **Real-Time Sparkline Charts**
+- CPU usage shown as percentage with sparkline history
+- Memory usage with bar visualization
+- Disk I/O with read/write graphs
+- Network traffic with up/down visualization
+
+### 3. **Color-Coded Information**
+- Green for normal values
+- Yellow/Orange for warnings
+- Red for critical values
+- Subtle color gradients in graphs
+
+### 4. **Compact Information Display**
+- Multiple metrics per line (e.g., "CPU: 23.4% | Temp: 45°C")
+- Efficient use of terminal space
+- Clear visual hierarchy
+
+### 5. **Live Process Monitoring**
+- Sortable process list
+- Real-time updates
+- Resource usage per process
+
+## Application to StreamLens
+
+### Enhanced Flow Analysis View
+```python
+# Inspired by TipTop's layout
+class FlowAnalysisEnhanced(Container):
+    def compose(self):
+        # Left panel: Flow summary with sparklines
+        with Vertical(id="flow-summary", classes="column"):
+            yield Static("Flow Overview", classes="header")
+            yield FlowMetricsPanel()  # Total flows, packets, volume
+            yield SparklineChart(id="flow-rate")  # Flows/sec graph
+            
+        # Center panel: Main flow table with mini-graphs
+        with Vertical(id="flow-table", classes="column-wide"):
+            yield EnhancedFlowTable()  # DataTable with inline sparklines
+            
+        # Right panel: Selected flow details
+        with Vertical(id="flow-details", classes="column"):
+            yield Static("Flow Details", classes="header")
+            yield FlowTimingChart()  # Inter-arrival timing graph
+            yield ProtocolBreakdown()  # Pie chart of protocols
+```
+
+### Real-Time Metrics with Sparklines
+```python
+class FlowSparkline(Widget):
+    """Mini inline chart for flow metrics"""
+    
+    def render(self) -> Text:
+        # Create ASCII sparkline like TipTop
+        values = self.get_recent_values()
+        spark = self.create_sparkline(values)
+        return Text(f"Rate: {self.current_rate:>6.1f} pps {spark}")
+```
+
+### Enhanced DataTable Row Format
+Instead of static columns, include inline visualizations:
+```
+Flow  Source           Proto  Destination      Volume  Rate  Quality  Timing Graph
+  1   192.168.1.1:80  TCP    10.0.0.1:443    1.2GB   ████  95%     ▁▃▅▇█▅▃▁
+  2   10.0.0.2:53     UDP    8.8.8.8:53      450MB   ██░░  87%     ▇▇▅▃▁▁▃▅
+```
+
+### Color-Coded Quality Indicators
+```python
+def get_quality_style(quality: float) -> str:
+    if quality >= 90:
+        return "bold green"
+    elif quality >= 70:
+        return "yellow"
+    else:
+        return "bold red"
+```
+
+### Live Update Pattern
+```python
+class StreamLensApp(App):
+    def on_mount(self):
+        # TipTop-style periodic updates
+        self.set_interval(0.5, self.update_metrics)  # 2Hz for smooth graphs
+        self.set_interval(1.0, self.update_flows)    # 1Hz for flow data
+        
+    def update_metrics(self):
+        # Update sparklines and real-time graphs
+        for widget in self.query(SparklineChart):
+            widget.add_data_point()
+```
+
+### Compact Header Bar
+```
+StreamLens | Flows: 127 | Packets: 1.2M/s | Volume: 845MB/s | Enhanced: 12 | Outliers: 3
+```
+
+### CSS Styling Inspired by TipTop
+```css
+/* Dark theme with accent colors */
+Screen {
+    background: $surface;
+}
+
+.column {
+    width: 25%;
+    padding: 1;
+    border: solid $primary-lighten-3;
+}
+
+.column-wide {
+    width: 1fr;
+    padding: 1;
+}
+
+SparklineChart {
+    height: 3;
+    border: none;
+}
+
+.metric-good { color: $success; }
+.metric-warning { color: $warning; }
+.metric-critical { color: $error; }
+
+/* Subtle animations for live updates */
+.updating {
+    background: $primary 10%;
+    transition: background 200ms;
+}
+```
+
+## Implementation Priority
+
+1. **Phase 1**: Add sparkline charts to flow table
+2. **Phase 2**: Create multi-column layout with live metrics
+3. **Phase 3**: Implement inline bar charts for volume/quality
+4. **Phase 4**: Add color-coded alerts and thresholds
+5. **Phase 5**: Create smooth animations for updates
+
+## Benefits
+- **Information Density**: Show more data in less space
+- **Visual Clarity**: Instant understanding of trends
+- **Professional Look**: Modern monitoring aesthetic
+- **User Experience**: Smooth, responsive interface
+- **Real-Time Insight**: Immediate visibility of changes

+# Wide Grid Layout Improvements
+
+## Enhanced Column Specifications
+
+The grid view has been significantly widened to ensure proper column alignment and readability:
+
+### Column Width Changes
+
+| Column | Old Width | New Width | Alignment | Description |
+|--------|-----------|-----------|-----------|-------------|
+| # | 2 chars | 3 chars | Right | Flow number |
+| Source | 20 chars | 24 chars | Left | IP:port source endpoint |
+| Proto | 6 chars | 8 chars | Left | Transport protocol (UDP, TCP, etc.) |
+| Destination | 20 chars | 24 chars | Left | IP:port destination endpoint |
+| Extended | 10 chars | 12 chars | Left | Extended protocol (CH10, PTP, etc.) |
+| Frame Type | 12 chars | 15 chars | Left | Specific frame type |
+| Pkts | 6 chars | 8 chars | Right | Packet count |
+| Volume | 8 chars | 10 chars | Right | Data volume with units |
+| Timing | 8 chars | 10 chars | Right | Inter-arrival timing |
+| Quality | 8 chars | 10 chars | Right | Quality percentage/status |
+
+### Total Width Calculation
+
+- **Previous total**: ~93 characters
+- **New total**: ~124 characters 
+- **Width increase**: ~33% wider for better readability
+
+## Alignment Improvements
+
+### Source and Destination Fields
+- Increased from 20 to 24 characters
+- Supports longer IP addresses and port numbers
+- Truncation threshold increased from 18 to 22 characters
+- Better accommodation for IPv4 addresses with high port numbers
+
+### Right-Aligned Numeric Columns
+- All numeric columns now have 2 extra characters of width
+- Ensures proper right-edge alignment for:
+  - Packet counts (up to 99,999,999)
+  - Volume with units (up to 999.9MB)
+  - Timing values (up to 99.9s)
+  - Quality percentages (up to 100.0%)
+
+### Visual Hierarchy
+- Sub-rows now use 4-character indent to match wider flow number column
+- Perfect alignment maintained between main flows and sub-rows
+- All columns line up precisely regardless of data content
+
+## Layout Example
+
+```
+  #   Source                   Proto    Destination              Extended     Frame Type        Pkts    Volume      Timing     Quality
+  1   192.168.4.89:1024       UDP      239.1.2.10:8080         3 types      Mixed             1452      1.9MB      77.8ms     Enhanced
+                                                                CH10         CH10-Data         1110     1.44MB       102ms       76.4%
+                                                                CH10         TMATS              114      148KB       990ms        7.8%
+                                                                             UDP                228      296KB       493ms       15.7%
+```
+
+## Technical Changes
+
+### Formatting Functions Updated
+1. **`_format_flow_summary_line()`**: Updated to use new column widths
+2. **`_format_protocol_frame_line()`**: Updated to match main flow alignment
+3. **Header formatting**: Expanded to accommodate wider columns
+4. **Truncation logic**: Removed `[:width-8]` constraints that were cutting off data
+
+### IP Address Handling
+- Source/Destination truncation increased from 10 to 14 characters before ellipsis
+- Better support for longer IP addresses and port combinations
+- Maintains readability while showing more endpoint information
+
+## Benefits
+
+1. **Perfect Column Alignment**: All numeric columns now line up properly on their right edges
+2. **No Data Truncation**: Removed width constraints that were cutting off information
+3. **Better Readability**: Increased spacing makes complex flow data easier to scan
+4. **Professional Appearance**: Wider grid looks more polished and organized
+5. **Future-Proof**: Accommodates longer protocol names and extended data
+
+The wide grid layout ensures that complex telemetry flow analysis is presented in a clear, professional format that makes the hierarchical protocol breakdown easy to understand at a glance.
