Not too sure about the tank addon as when I heal our tanks go in group 1, so they are all together anyway. However the yellow text on the buffs would be almost any buff addon, just have the text moved up onto the actual buff, I'm using Satrina Buff Frames, so give that a go and see if you can do it with that, else try a few other buff addons out there.
The MainTank list is a feature of oRA2, as is the Cooldowns Tracker.
Not sure about the buff addon, could be any number of things.
Thank you very much guyes
uses Ora2 for tank frames and OmniCC for cooldowns
