Yellow Keycard Flatpaks

This is a repository holding some Flatpak builds I've assembled which I have yet to submit to Flathub for a variety of reasons - the app is still going through developer changes and approval, the developers have gone missing or retired so I can't get approval for a submission, or the licensing situation is unclear or incompatible with Flathub, or the developers have specifically said they don't want their app to be listed on Flathub.
