How to turn tooltips for party?

[vicont]

Well, while instancing I turn off name plates and adjust my interface as clean as possible, in order to have the best view around me.

Yet, while in heat of combat, tooltips for party members don't have any sufficient role, I already know everything I have to know about the people I play with.

So, maybe there's some sort of addon to turn tooltips off while being in party or raid?
