I have used that UI for awhile, I like the colors theme and layout. But it has really suffered since it's last update. There are elements of the UI that don't work anymore, I'm sorry but I can't remember all of them at this moment, but enough that I quit using it totally. I went with pieces of UI that did what I needed them to do and that's it (minimal). That way when patch day rolls around, I am not scrambling to get updates on stuff that's broke. Learned this from 10 years of playing WoW lol.
