Small kiosk-mode for floating group live video chat window
Your competitor has this already. Sometimes as a user you want to see the faces of the folks you are meeting and chatting with while looking at your own (non-shared) desktop. As far as I can tell, current video windows don't minimize very small at all and thus take up a significant amount of screen real estate. Minimizing to a small strip of video windows that floats in front of other applications would be a very useful feature. Multitasking -- for example, listening to and watching a group video call out of the corner of your eye while working on an unrelated task of developing a ppt presentation -- is a common use case.
