I've got my UI pretty well back up to speed. I have to shuffle a few things about due to some of the changes brought about by the 'no opening buttons during combat' rule. I didn't use any keys that made mid-combat decisions for me, but did have one that performed different acitions based solely on which pet I had summoned. So, it's not quite where it was, but it's 95% of the way back, and I don't feel that it gets in the way anymore, like the default UI does.
