This is some really nice work! However, I do have a request (and a report of a very major bug).
In the 3 bars caster installation (perhaps others, but this one for sure), several of the bars are locked into the same keybinding. While different abilities can be put on these bars, what appears to be a copy of another keybind is placed on the bar, while the button itself remains unbound. I believe this has something to do with the bars you put into the layout.
In any of the caster installations, it would be fantastic if you would include the option of having the extra block of 6 buttons go on the right side, as I would very much like my chat box to be where it is currently! I have tried doing this myself but cannot figure out which view file corresponds to this bar.
Other than that, this looks great and I certainly prefer this over fire UI. One of the best UIs overall I've seen released yet!
P.S. Now that I think about it, is it possible to have a version which blanks out the menu icons (guild management, pvp window, and the other menu with feats inventory etc buttons?) Some of us have them keybound and don't need/want it cluttering up our screen.
P.P.S. If someone tells me where AoC is storing my screenshots, I'd be happy to share.
