i agree with the flatpak, sadly this will probably not change.
BUT! if you are a developer, you could run with distrobox graphically applications from the distrobox from OpenSUSE!
I am starting to use this on tumbleweed and there are even "exporters" so the app in the distrobox will be exported to your application menu on the metal!
Does that app have access to a full terminal ? Like if I install vs code inside distrobox, will it have access to the systems or the container terminal?
