If you want your UI to look like this you need to install:
-ElvUI
-LocationPlus for ElvUI
-BenikUI
-AddOnSkins
-Shadow & Light
Optional:
-Details!
-Masque: Shadow
-WeakAuras by Luxthos
Follow the installation when you log in and then copy my string.
I also use DBM, Mapster, KUI nameplates, Easy Scrap, GatherMate and Faster Loot addons.
