I’ve thought a lot about the general “back” button that has confused our less experienced users, and for now, the only thing I’ve come up with is to improve and unify as much as I can the styles of those “back” buttons (which vary depending on whether they are shown in Docs, Profile, or Chats).
Hopefully, a definitive and more robust solution will come along. I think it’s the only major pending improvement needed in Discourse’s UI/UX at a general level, so it can be used by “the average user” with no friction anymore.
