4. Added new methods:
   - `apply(theme:)`: Applies all settings from a selected theme
   - `saveTheme()`: Saves current settings as a new theme

### **MoveResizeAppearanceView.swift**
**Changes:**
1. Added state variables for theme management:
   - `showThemesList`: Controls theme list sheet presentation
   - `showSaveAlert`: Controls save theme alert
   - `themeNameToSave`: Stores the name when saving a theme
   - `themeStore`: Instance of `MoveResizeThemeStore`

2. Updated bottom bar to include:

   - "Save Current Theme" button (⌘S shortcut)
   - Existing "Reset to Defaults" and "Close" buttons

3. Added sheet and alert modifiers:
   - Sheet presents `MoveResizeThemesListView`
   - Alert prompts for theme name when saving

4. Added new methods:
   - `apply(theme:)`: Applies all settings from a selected theme
   - `saveTheme()`: Saves current settings as a new theme

## Key Features

### Independence
- Each tab (Layout Appearance, Window Switcher, Move/Resize) has its own:
  - Theme model
  - Theme store
  - Theme list view
  - UserDefaults storage key
- Themes cannot be shared between tabs (as requested)
- Settings are completely independent

### User Interface
- Consistent UI across all three tabs
- "Manage Themes…" button opens a modal sheet showing saved themes
- "Save Current Theme" button (⌘S) prompts for a theme name
- Theme list displays:
  - Color previews for quick identification
  - Creation date
  - Apply, Rename, and Delete actions

### Data Persistence
- All themes are stored in UserDefaults
- JSON encoding/decoding for reliable serialization
- Automatic persistence when themes are added, removed, or renamed

## Usage

### Saving a Theme
1. Configure appearance settings in any of the tabs
2. Click "Save Current Theme" or press ⌘S
3. Enter a name in the alert dialog
4. Click "Save"

### Managing Themes
1. Click "Manage Themes…"
2. View all saved themes with previews
3. Click "Apply" to load a theme
4. Click "Rename" to change a theme's name
5. Click the trash icon to delete a theme

### Applying a Theme
1. Click "Manage Themes…"
2. Find the desired theme in the list
3. Click "Apply"
4. The sheet closes and all settings are updated

## Storage Keys
- Layout Appearance: `"savedThemes"` (existing)
- Window Switcher: `"savedSwitcherThemes"` (new)
- Move/Resize: `"savedMoveResizeThemes"` (new)

## Next Steps
To use these files in your Xcode project:
1. Add all 6 new Swift files to your project
2. Ensure they're included in your target
3. Build and run
4. Test theme saving/loading in both tabs

The implementation follows the same patterns as the existing Layout Appearance theme system, ensuring consistency and maintainability.
