Describe the feature

Hey, i would love to see Buffs/Debuffs on the Targets Target. Especially interesting for Tanks to see the Debuffs on the Tank who has Aggro from the Boss.

Describe the implementation

Just like the Player/Target Frame

TargetTarget events are "unit less" events, meaning you need to listen to all events instead of being able to listen to a specific units events.
This is not very performant and would require some throttling to be implemented properly for these types of units. As to not be too big of a performance hit. (There are a lot of aura events in a raid group as example)

Not saying it won't be implemented, just that it will be a while before I tackle that.
