Hi @kawaiipunk wrt to the configurations, yesterday we noted that the screen is unmirrorred, and we lack the option to mirror. IIRC previously we will have had “mirror by default” your own webcam, to make it feel more natural to participants.
Then there is the default whiteboard. We had collectively developed this one: meet.coop_default_whiteboard_screen_15-06-22.jpg - Nextcloud (I see that Collocall also followed the logic of presenting a whiteboard that immediately helps newcomers to find the main buttons ;-))
If you make me BBB admin again, I can help out with some of the UI configurations.
