-**Claude Assistant**: Development completed for v1.7.8 with critical bug fixes:
-1. **File Association Fix**: Fixed command-line argument parsing to properly detect packaged vs development mode using `app.isPackaged`, enabling files to open correctly on first double-click in packaged app
-2. **Print Preview Fix**: Completely rewrote print handler to rely on CSS `@media print` rules instead of manual DOM manipulation, ensuring preview content (not toolbar) is printed
-3. **Code Cleanup**: Removed auto-opening DevTools for production-ready build
