Kate on Flathub
I've just got to https://github.com/flathub/org.kde.kate/pull/23 which I think is sad. If we stop packaging application on Flathub as soon as one use case from the classic version stops working then I guess we can remove KDevelop and some others where some features are not working.
I don't have a solution nor time to fix those issues right now but I don't think this is the right direction.
