Keith Smith 19f7c7faec Implement custom layout persistence
Features:
- Custom layouts now saved to ~/.local/share/gridsnap/layouts.json
- Layouts automatically loaded on extension initialization
- Layouts persist across Cinnamon restarts and extension reloads
- Only custom layouts saved to file (default layouts remain in code)
- Added GLib and Gio imports for file operations
- Error handling for file read/write operations

Technical implementation:
- _loadLayouts(): Merges default layouts with saved custom layouts on startup
- _saveLayouts(): Extracts and saves only custom-* layouts to JSON file
- Automatically creates storage directory if it doesn't exist
- Called when user saves a layout in the graphical editor

GridSnap TODO List

Critical Issues

1. Custom Layout Persistence COMPLETED

Priority: High

  • Custom layouts are only stored in memory
  • Layouts are lost when extension reloads or Cinnamon restarts
  • Need to implement file-based storage
  • Location: ~/.local/share/gridsnap/layouts.json
  • Save layouts when created in graphical editor
  • Load layouts on extension initialization

2. Remove Last Zone Implementation (extension.js:236-274)

Priority: Medium

  • _removeLastZone() destroys and recreates entire editor interface
  • Causes visual flicker
  • Inefficient approach
  • Could leave dangling event listeners
  • Refactor to only remove the last zone widget without recreating everything

Functionality Improvements

3. Multi-Monitor Support

Priority: High

  • Currently only works on primary monitor (extension.js:61)
  • Need per-monitor zone configurations
  • Detect which monitor window is on when snapping
  • Allow zone editor to work on any monitor
  • Store zone layouts per monitor

4. High-DPI Display Support

Priority: Medium

  • Coordinates from get_coords() may not respect window scaling
  • Test on high-DPI displays
  • Verify zone calculations work correctly with display scaling
  • May need to use get_resource_scale() or similar

5. Edit Existing Custom Layouts

Priority: Medium

  • Currently can only create new layouts in editor
  • Add ability to select and edit existing custom layouts
  • Add UI to choose which layout to edit
  • Pre-populate editor with existing zones when editing

Code Quality & Robustness

6. Comprehensive Error Handling

Priority: Medium

  • Add validation of zone sizes during window snapping
  • Add checks for window.move_resize_frame() success
  • Validate monitor dimensions before calculations
  • Handle edge cases (window too small, zone too small, etc.)
  • Add user notifications for errors instead of silent failures

7. Event Leak Prevention

Priority: Low

  • Zone preview widgets might not be properly destroyed if motion events stop unexpectedly
  • Audit all signal connections and ensure disconnect in cleanup
  • Add defensive cleanup in edge cases
  • Review overlay widget lifecycle

8. Zone Overlap Detection

Priority: Low

  • Warn user if zones overlap in graphical editor
  • Provide visual feedback for overlapping zones
  • Optionally prevent overlaps or auto-adjust

Features from README (Planned)

9. Zone Layout Import/Export

Priority: Low

  • Allow exporting custom layouts to JSON files
  • Import layouts from JSON files
  • Share layouts between systems
  • Backup/restore functionality

10. More Pre-configured Layouts

Priority: Low

  • Add more default layout options
  • Common patterns: ultrawide monitor layouts, vertical splits
  • 1/3 - 2/3 layouts
  • Picture-in-picture style layouts

11. Animation Effects

Priority: Low

  • Add smooth transitions when snapping windows
  • Animate zone overlay appearance/disappearance
  • Visual feedback when window snaps to zone

12. Settings Panel

Priority: Medium

  • Add Cinnamon settings panel for the extension
  • Allow customization of keybindings
  • Configure animation speeds
  • Toggle features on/off
  • Manage saved layouts (delete, rename, reorder)

Documentation

13. Update Metadata

Priority: Low

  • Add "url" property to metadata.json (currently shows warning)
  • Update author name from "Your Name" to "Keith Smith"
  • Add project URL/repository link

Testing

14. Test Coverage

Priority: Low

  • Test on different Cinnamon versions (5.0, 5.2, 5.4, 5.6, 6.0)
  • Test with different window types (maximized, minimized, dialog boxes)
  • Test edge cases (dragging between monitors, rapid key presses)
  • Test with different keyboard layouts
  • Verify memory leaks don't occur with repeated enable/disable

Recently Fixed

  • Keybinding closure bug (all zones mapped to zone 9)
  • Keybinding conflicts with panel app launcher (changed to Super+Ctrl+1-9)
  • Shift-drag detection (implemented modifier polling)
  • Window object reference (use global.display.focus_window)
  • Window API compatibility (property checks vs get_maximized())
  • Signal handler parameters (grab-op-begin/end)
  • Laptop keyboard support (removed numpad dependency)
