Can't Find MOD
Okay .. I used to have this mod that .. if I was in a Group/Raid... as I tabbed to the next Target (Without using a macro) it would "Automaticly" change the Icon above said targets head to lets say the Skull Icon. and then once I tabbed to the next target it would put the skull over That targets head.. So on and So forth .. GREAT addon for groups that have a tuff time focusing DPS. I KNOW IT EXISTS. I had it at 1 point .. but for the life of me I can't remember what it was called. +10 rep for anyone that can help me out.
