I don’t even WANT to go into how long this took me to put together. Trying to find the mod to make that little background-bar-thingie was like pulling teeth. WoWInterface’s search engine is only good if you know the name of the addon you want.
But there it is, my labor of love. I made this after trying out Spartan UI v2 and not being altogether pleased with my lack of pet’s target window, lack of a good buff window, and having my portrait and targets at the bottom of the screen.
Edit:
Here’s the final UI at the beginning of Kara. I added Aperture to my list of addons for that black bar at the bottom (basically it negates that part of the screen and modifies the size of WoW window).


Looks Nice. Mine is kinda like that. I agree its a pain in the butt trying to piece together a UI.
The new UI looks really good.
Onawar, remind me to ask you in BA chat what the add-on is that shows your Steady Shot timer.
