+# Plugin Redesign - Version 4.0
+
+## 🎉 Major Improvements
+
+This redesign brings significant UX improvements, better performance, and more flexible sync options.
+
+---
+
+## ✨ New Features
+
+### 1. **Improved Settings UI**
+
+#### Tab-Based Organization
+Settings are now organized into clear tabs:
+- **General**: Default settings, scan directory, ignored files
+- **Note Types**: Configure note type mappings with searchable table
+- **Folders**: Folder-specific deck and tag settings with search
+- **Syntax**: Customize syntax markers
+- **Advanced**: Actions and import/export settings
+
+#### Searchable Tables
+- Both Note Types and Folders tables now have search functionality
+- Quickly find specific note types or folders without scrolling
+
+#### Folder Picker
+- **Browse Button** next to Scan Directory field
+- Visual folder selection instead of typing paths
+- Prevents typos and makes configuration easier
+
+#### Import/Export Settings
+- **Export** your settings to JSON file for backup
+- **Import** settings from JSON file to restore or share configurations
+
+---
+
+### 2. **Flexible Sync Commands**
+
+Three new sync options with keyboard shortcuts:
+
+| Command | Description | Use Case |
+|---------|-------------|----------|
+| **Sync Current File** | Sync only the active file | Quick updates to single file |
+| **Sync Current Folder** | Sync all files in current folder | Work on specific project/topic |
+| **Sync Entire Vault** | Sync all files (or scan directory) | Full sync (existing behavior) |
+
+**How to use:**
+1. Via Command Palette (Ctrl/Cmd + P):
+   - "Obsidian to Anki: Sync Current File"
+   - "Obsidian to Anki: Sync Current Folder"
+   - "Obsidian to Anki: Sync Entire Vault"
+
+2. Via Context Menu (Right-click):
+   - Right-click on any markdown file → "Sync to Anki"
+   - Right-click on any folder → "Sync Folder to Anki"
+
+3. Via Ribbon Icon (same as before):
+   - Click the Anki icon to sync entire vault
+
+---
+
+### 3. **Progress Tracking**
+
+#### Visual Progress Modal
+- Shows real-time progress during sync
+- Displays current operation status
+- Shows percentage and file counts
+- Can be cancelled if needed
+
+#### Status Bar Indicator
+- New status bar item shows sync state:
+  - 📝 **Anki** - Idle, ready to sync
+  - 🔄 **Syncing...** - Sync in progress
+  - ✅ **Synced** - Sync completed successfully (3s timeout)
+  - ❌ **Error** - Sync failed
+
+---
+
+### 4. **Performance Improvements**
+
+#### Better File Processing
+- Shows number of changed files before processing
+- Skips unchanged files (using hash comparison)
+- "No changes detected" notification when nothing to sync
+
+#### Improved Error Handling
+- Clear error messages when Anki is not running
+- Better feedback on connection issues
+- Graceful degradation on errors
+
+#### Batch Processing
+- Files are processed in optimized batches
+- Progress updates show current batch
+
+---
+

+
+### Better Feedback
