Revamping the UI

I've taken to revamping my UI, right now still playing around with a few things, but here's the current setup:

Addons I'm currently using:

PitBull: Portraits, party, group bars
Quartz: Cast bars and swing timer
Elk's Buff Bars: Buffs and Debuffs
Omen
Recount
CT Viewport: Gives the nice black background on the bottom
Simple Minimap: Minimap addons
Dominoes: Buttons, bars, etc.
Minimap Button Frame: Pulls all my minimap buttons into the frame on the bottom right

And I use Addon Control Panel to manage all of them.

Now, to put all my tanking buttons in the right spots...
