I have would like be to be able to click a window and bring it to the front.
Often people dial in via phone for audio to prevent the infinite echo issue, but then since
they're quiet the window stays tiny.
When there are multiple rooms of people joined, it would be really nice to be able to manually choose which video signal fills the screen. Often times, people in a large room appear very small and it's difficult to see their body language when the video is so small.
