- Implement PDF and PDF thumbnail generation with incremental loading
- Add UI refresh mechanism (tick counter + RefreshView message)
- Improve fl! macro with named parameters
- Clean up code organization (mod.rs: wiring, model.rs: state only)
Add ability to set current image as desktop wallpaper with keyboard
shortcut 'W' and icon button in Properties panel.
Supports COSMIC, GNOME, KDE, XFCE, and tiling window managers via
automatic detection and fallback mechanism.
Implementation uses wallpaper crate with custom COSMIC config file
integration and gsettings/feh fallbacks.
Both SVG and PDF support are prepared in code structure but
not yet functionally implemented. They currently show 1x1
placeholder images. Moved to 'Planned Features' section with
proper status documentation.
Document all implemented and planned features:
- Current features with implementation status
- Planned features organized by priority
- Technical architecture details
- Keyboard shortcuts reference
- Contributing guidelines for new features
