Even if you don't use a full overhaul, you have to have some addons that change the way your interface looks!

Addons used (http://imgur.com/afjv7): Wowhead Looter, Bartender4, Bison, CLCRet, DeadlyBossMods, Leatrix_Plus, Leatrix_Tooltip, Omen, OmniCC, Recount, ShadowedUnitFrames, SharedMedia (not currently used.), TomTom, WIM, and a custom minimap (I called my version 'QuickMap') addon I adapted from another addon to remove all the functionality I didn't need, as well as swap the configuration variables to directly passed values to reduce the overhead involved. I plan to do this with all the addons I use.
