I’ve been involved with Linux for a long time, and Flatpak almost seems too good to be true:
Just install any app on any distro, isolated from the base system and with granular rights management. I’ve just set up my first flatpak-centric system and didn’t notice any issues with it at all, apart from a 1-second waiting time before an app is launched.
What’s your long-term experience?
Notice any annoying bugs or instabilities? Do apps crash a lot? Disappear from Flathub or are unmaintained? Do you often have issues with apps that don’t integrate well with your native system? Are important apps missing?
Well, Flatseal is using flatpak’s standard way of managing permissions. Everything it does you can also do from the command line with flatpak. It’s just a frontend.
I think KDE wants to add these options to it’s settings as well. That will be great, when it’s better integrated into the whole system.
KDE already does have the same thing in its settings
