I have not been playing much lately, so I am afraid the UI has been suffering a lack of attention. The regular 1280x1024 version should be up to date, but the other resolutions and mods may not be.
However, if new spell and buff slots are added, you can be sure I will get those in ASAP.
Somehow my beta application for EQ2 got misplaced, so I am not in that, and thus not doing any UI work for it.
I am also not in the OoW beta, so I won't have a headstart on UI changes for that unless they show up on the test server when I have time to anticipate them.
