## 🚀 BIGGEST ACHIEVEMENT: RENAME FEATURE COMPLETE ⭐

**THE PROBLEM**: 
- Delete button worked ❌
- Rename button showed up in UI but did nothing ❌
- Users complained they couldn't rename files ❌

**THE FIX**:
```javascript
// Added to js/main.js:
✓ openRenameModal() method    → Opens rename dialog
✓ renameItem() method          → Performs the rename
✓ Keyboard shortcuts           → Enter to confirm, Escape to cancel
✓ Proper validation            → Prevents invalid names
✓ UI integration               → Works with folder dropdown
✓ Error handling               → Shows user-friendly messages
```

**NOW**: Users can right-click any file/folder → "Rename" → Works perfectly! ✅
