A very clean and minimal ElvUI profile I made with tanking in mind, but can be used for any class/spec.
Extra hidden hover-over action bars are located just to the left of my damage meters.
Updated: 01/23/18 -- Raid frames sorting is more friendly so you don't see offline (unless in default groups) or people outside the of the main groups. By default you should now see your target's target and focus raid debuffs.
