Hey great addon set! I just have two minor bugbears.
First, when I'm on my character screen and hover over an item slot while holding alt, it of course shows every piece of gear I have in my bags of that particular slot. Usually I can equip them right from there, but it's not allowing me to with RealUI for some reason.
Second, while in LFR last night (not sure if it happens in regular (both Mogu'shan and Heart of Fear) the maps were fine but the boss icons were way off where they should be on the maps.
Other than those two things, the mod looks really great and very functional.
edit: Nevermind on both counts! EJ Icon Scale in Mapster options needed to be adjusted to put them in the right spot, and the other problem fixed itself.
