I switched from Windows to Fedora to give Linux another chance.
I think a Flatpak or RPM would make the program more accessible.
Of course, the effort involved has to be reasonable ;)
I use your software and am quite satisfied so far.
I'm not entirely sure if this is the right place, but if possible, it would be a great addition if entire ISO files (some old DVDs) or at least VOB files could be converted.
The best option would be a setting to directly upscale entire DVDs to Blu-ray 4K, including all menus and everything else.
