Huh? It does work lol, there’s flatpak uninstall --unused --delete-data
(and you can also pass --delete-data
when uninstalling individual Flatpaks, to be more selective), this is just someone’s new GUI app to do the same thing, and you could already do it through KDE Discover for example
What do you mean? I’ve never had a problem with it on KDE, Fedora at least
