You're right! There's an issue with the resizing logic. The problem is that I'm using e.clientX directly as the width, but it should be calculated relative to the panel's position. Let me fix the resizing functionality:

The key fixes I made:

1. Proper Width Calculation: Now using deltaX (difference from start position) instead of absolute clientX
2. Start Position Tracking: Added startX and startWidth to track where the resize began
3. Better Cursor Management: Added visual feedback with cursor changes and prevented text selection during resize
4. Flex Shrink Control: Added flexShrink: 0 to prevent panels from shrinking unexpectedly
5. Visual Feedback: The resize handle now changes color when actively resizing

The resizing should now work smoothly for both the chat panel and the file explorer within the IDE!

I detected and automatically synced new changes from main in -ASDA-.
