Video & Voice UI Design Concept.

I believe I have a concept that may come in useful. As the current User Interface goes, in terms of calls, it primarily shows users with enabled video first and those without after, however, this causes a small browser/app to be split into four rectangular feeds. For example, I was recently in a Video Call with myself and three other users where two enabled feeds were in place and the remaining feeds were not active, but still displayed. My concept would consist of enlarging the enabled video feeds to allow them to better fit horizontally, while then downsizing the users with disabled video and removing the rectangular design, replacing it with a circular icon format, which would then be placed in the area below the enlarged feeds without hindering the User Interface.
