At first: I don't know what tag should be used for this so "Feedback" seems the best for me.
Hello guys, I really miss a Mattermost package in eopkg. Unfortunately I must use a generic package from a .tar.gz or a .AppImage. The problem is that I don't have auto updates there but I also try to avoid Snaps and Flatpaks that much I can because I don't like container software. I experienced performance and permission issues with Snaps and Flatpaks really often.
