1. ID Sanitization

• Fixed frame type IDs that contained special characters (-, :)
• Ensures CH10-Data becomes CH10_Data in IDs
• Fixed all queries to use sanitized IDs consistently

2. Stats Panel Updates

• Changed from direct _renderable manipulation to proper update method
• Added update_content() method to properly refresh statistics
• Stats panel now properly displays data after loading

3. CSS Tab Layout

• Added proper CSS for horizontal tab bar display
• Set dock: top for tab bar positioning
• Defined proper dimensions for tab content areas
• Split layout: 70% flow table, 30% stats panel

4. Data Refresh

• Fixed refresh_data() to use correct sanitized IDs
• Ensured all tabs refresh when data is loaded
• Stats panels now update with actual flow statistics

🎨 Expected Layout

┌─────────────────────────────────────────────────────────────┐
│ [Overview] [CH10-Data] [UDP] [PTP-Sync] [TMATS] [IGMP]     │ <- Horizontal tab bar
├─────────────────────────────────────────────────────────────┤

│                                                   │         │

📊 Tab Content Structure

Each frame-type tab shows:

Left Side - Flow Table (70%)

• Flow ID, Source/Dest IPs and ports
• Protocol and packet counts
• Timing statistics (avg/std deviation)
• Outlier counts and quality scores

Right Side - Stats Panel (30%)

• Total flows with this frame type
• Total packet count
• Aggregate timing statistics
• Overall outlier rate
• Average inter-arrival time

🔧 Technical Changes

1. Sanitized widget IDs: table-CH10_Data instead of table-CH10-Data
2. Proper CSS selectors: Using > for direct children
3. Fixed dimensions: Explicit width percentages for layout
4. Update mechanism: Proper content refresh methods

🎯 Next Steps

If tabs are still appearing stacked:

1. The Textual version might need specific tab layout directives
2. May need to check if TabbedContent is being properly initialized
3. Could add explicit layout constraints in compose()

The data should now refresh properly when the PCAP is loaded!
