EverQuest II doesn't have a bad one by any means, but the designers apparently aren't content with the current setup. They're already promising major changes to hit the test server in just over a week -- to coincide with game update 57 -- and among the many mechanical changes going along with the update will be a major UI overhaul.
A post earlier today by lead programmer Greg "Rothgar" Spence confirmed that the team is re-skinning the default interface, as well as modifying several windows alongside it. While he's scant on providing exact details, he promises that players will get a chance to experience everything on the test servers very shortly. Although there are some concerns in the the thread regarding what the changes might mean for existing custom UIs, most seem cautiously optimistic. EverQuest II players should be ready for the test server in just over a week, with the patch likely not too far in the future past that.
