Implementing File List Collapse/Expand Feature ✅

Successfully added collapse/expand functionality to the file list panel!

Tasks Completed

• Analyze current file list UI structure
• Review relevant JavaScript modules (fileManager.js)
• Implement collapse/expand toggle button
• Add state persistence (localStorage)
• Update CSS for smooth transitions
• Commit and push changes
• Provide PR creation link

Implementation Summary

Added a collapse/expand feature for the file list panel with the following capabilities:

UI Components:

• Toggle button (◀) in the file list header for collapsing/expanding the panel
• Minimized restore button (▶) appears on the left side when collapsed
• Smooth slide animation using CSS transforms for a polished user experience

Functionality:

• State persistence using localStorage (fileListCollapsed key)
• Automatic state restoration when reloading the page
• Full dark/light theme support with styled buttons
• Responsive design - properly hidden on mobile devices (<768px)

Code Changes:

• index.html: Added toggle button and minimized restore button
• fileList.css: Added collapse/expand styles, animations, and button styling
• fileManager.js: Implemented toggle logic with state management

The implementation follows the same design pattern as the existing output panel toggle for consistency across the application.

Files Modified

• /SharpPad/wwwroot/styles/fileList.css - Added styles and animations
• /SharpPad/wwwroot/fileSystem/fileManager.js - Added toggle functionality
