Yeah I think we need something like Gitea has:

I think that's best built into the api as a "Demo mode" setting. That setting would disable a few things as well on the api side.

Maybe not as ugly, but yes. I have the feeling that some users don't get that they look at something public.

Also: is it possible to register an account? If so that should probably also be disabled in demo mode.

I just realize that we should probably separate the user and pw hint from the demo instance reminder.
