Try to still all your desktop apps through Flatpak. Flatpak applications are sandboxes (meaning they are regulated by the system using permission toggles and variables). It is better for security/privacy, and makes transferring app data to a new OS install easy (app data is stored in ~/.var/app/
)
Application sandboxing is just SO important. If the app isnt available as Flatpak, you could install it normally and use Bubblejail to restrict it.
What specifically don’t you like about it?
