Volume slider

Could it be possible to add a master volume slider in an easy to access spot such as in the main UI? Sometimes I like to watch youtube videos while I play and the game volume is way too high compared to the volume youtube is able to put out. When I turn the system volume down I can't hear the video...you probably get the point.

Any info on this?

If you happen to be using Windows 7, you can open the volume tool, then hit 'mixer' and adjust the volume/mute of each individual program that is open. I would be open to an in-game slider and/or mute, but for the time being I just use this.

Well waddya know, learn something new every day man. Tyvm ^^
