Really awesome. They’re all contained within my home directory too, so when I swap distros I can just copy my home dir and all my installed apps are carried over that way. Super useful feature that never gets mentioned! The downside to flatpaks is having to use them for cli in any way is a huge pain.
There’s literally no need. It’s auto installed because everything is portable and most applications that launch .desktop files know to look for it’s directory.
I do, that doesn’t keep packages installed between distro reinstalls or swapping between entirely different distros. I’m talking about the actual packages and app data themselves that are contained in home.
Happened to me where I felt loss if enjoyment over any game, that it felt like a waste of time and a chore. That eventually passed, definitely find them fun again.
