Thought I'd give my 2 copper since I've been using AutoBar for an extremely long time now.
I was very happy Autobar went to Ace, but I got to say, this new config menu really bugs me, in terms of adding buttons/categories and ordering. I'll keep this short and sweet, and just say that I'll REALLY miss the drag and drop functionality of the config. Got a new quest item? I just drug it onto the autobar, and the next character that needed it, there it was.
