About Overwolf on TS3

Lads, i just wanted to ask if some of you know/use Overwolf on Teamspeak3.

What is this software and is it really useful when we use TS3 by playing H&D2 ?

Thanks for advices.

I installed it with TS3, but I never use it.

I think I tried it once, but I never really found it that useful. All it does is puts an overlay on the side of the screen, but it only supports certain applications.

Thanks Jacobston.

For me, it was very simple : One install, one try, one crash, one uninstall.
