This application is being rewritten (usability, coding practices, maintainability).

• UI
  • The UI toolkit was changed from fltk-rs to egui
  • Logic was simplified
• Processing
  • PDF manipulation now leverages MuPDF instead of Poppler (and related libraries)
  • Most of the transformations are done in-memory instead of creating several intermediate files
• General refactoring and libraries updates

• User friendly sandbox approach (MSIX with appcontainer on Windows, Flatpak on Linux, Entitlements on macOS)
• Unflexible Office document conversion on macOS (Lack of LibreOffice headless support)
  • One option is to attempt to use OnlyOffice instead of LibreOffice on all platforms (much more lightweight)
  • Another approach is to either embed Podman on macOS or bundle a Linux image (Virtualization framework)
  • A radical solution is to just drop macOS support

There are no releases yet, as there are current unresolved issues and pending decisions.
