Summary

Major UI refactor that improves code organization, enhances user experience, and introduces a modern control interface:

• Refactored ConfigBar into 5 modular section components for better maintainability

  • Centered play/pause controls with larger, more accessible buttons
  • Skip previous/next buttons
  • Menu button to open settings drawer

🔧 Component Refactoring

Created 5 new focused components from ConfigBar:

• QuickStartSection - Demo loading buttons (2x2, 32x32)
• FilesSection - Map and solution file inputs with download buttons
• SpeedControlSection - Animation speed slider
• ControlsSection - Restart, Loop, Fit View, Screenshot buttons
• DisplaySection - Display toggles (Agent IDs, Cell IDs, Paths, Goals, Vectors)

✨ New Features

• Close button in drawer top-right corner for better UX
• Improved keyboard shortcut handling with switch statement

🏗️ Architecture Improvements

• Better separation of concerns with isolated components
• More maintainable codebase

Note: This refactor maintains all existing functionality while significantly improving code organization and user experience.

This looks great! There are a few small things I would like to resolve before merging though.
