As for having the option during install or right after landing on the desktop, say as part of the Welcome app would be nice. I have Fish in EOS and have the Flatpak issue. My roommate however is on Manjaro still cause I haven't had the time to finish setting up his Garuda. In Manjaro he has never been on Fish, but the Flatpak issue is there. Looks to be mainly a Fish issue, but also some without Fish have the issue.
