# Modern TUI Column Layout Example

## Flow Analysis View (View 1)

The new column layout separates transport and extended protocols for clearer flow analysis:

```
 #  Source             Proto  Destination        Extended   Frame Type   Pkts  Volume  Timing   Quality
 1  192.168.4.89:1024  UDP    239.1.2.10:8080   CH10       CH10-Data    1452    1.9MB   77.8ms      95%
 2  11.59.19.204:319   UDP    224.0.1.129:319   PTP        PTP Sync      297   26.8KB  378.4ms    Normal
 3  11.59.19.202:4001  UDP    239.0.1.133:4001  -          UDP           113   17.4KB  999.4ms    Normal
 4  192.168.43.111:68  UDP    255.255.255.255:67 -         UDP            46    3.8KB    2.3s     Normal
 5  11.59.19.204:80    OTHER  224.0.0.22:80     -          IGMP            6     360B   13.9s     Normal
```

## 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

## 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
- 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

This layout provides clear protocol hierarchy from transport layer through specialized protocols to specific frame types.
