This is not a complete Nameplates-Mod. The only thing it does, is colorizing the default Blizzard-Nameplates based on threat. This is the only feature I miss on the standard nameplates, so I made this little addon. In DPS/Healer-Mode, nameplates of mobs you have aggro from are red, if you gain aggro, they are yellow and if they are tanked, they are green. For tanks the behavior is of course reversed.

There is one option for this Addon: Only activate it for tanks.
