I don't get the appeal of tabs. When I want to switch to buffer `xyz' I think "man I should switch to buffer `xyz'" and simultaneously press =C-x b= and start typing in `xyz' to which the completion system helpfully fills in the rest for me. This is a direct translation of my thoughts, unlike with tabs where you have to find the correct tab and it gets crowded and by the time you find it you forget what you wanted from that buffer anyway. Maybe the tab bar makes more sense, I do something like that with multiple frames using emacsclient, but even for that I see no point in the visuals.
