Looks like exactly what I've been looking for! Great work!

Do you have any plans to distribute a flatpak version? Especially for single person projects, it can save time on packaging and testing.

As I can see flatpak is popular, I could check it, but I can't promise it as I never used flatpak and I'm not using linux a lot.

Cardo bundles are automatically compiled using github actions, If there is a flatpak posibilitie that would be easy.

However, as I could see (I'm new releasing apps) the multiple Linux distros make that the github bundles (made with ubuntu 22.04 machines) don't work for all distros.

If you are on Arch Linux there is a package on AUR.
