I gotta say, this was the first UI for me since the duf/dart era, that was actually visually appearing enough to switch over to. I'm even thinking that there's a possible chance Blizzard saw your UI and used ideas for D3. I'm no longer using the UI but once in a while I switch out my Interface/WTF folders just to check what Roth UI has become so far.
The only thing that is bugging me right now is that there is no "big icon mode".
For people with high DPI monitors(94.34 PPI - WUXGA@24" or higher) the icons are not even bigger then the size of the nail of your little finger. (And as a result, this may lead to tunnel vision, especially for the main actionbar cooldowns
)
Yes, I'm aware of the ability to change art scales and I do that most of the time(I usually change 0.82 to something like 1.25). So a global setting to introduce a "big icon mode" would be awesome!
