When you have two people on stage (or more) and you want to set someone to full screen by double clicking on them - does not display their full video - it zooms into their video and crops off half of their video.
I think it would be best if you kept the same aspect ratio here?
E.g. if someone is sharing their screen you would want to see all of it.
Maybe if you double click to make a video larger, then either the other videos should move down a bit, so that the main video has the same aspect ratio, or the other videos move to be stacked on the right? (I think this is how restream.io do it?)
