Having your video screen only appear in the top right is quite limiting. It would be great if your screen (and a few others that may be in the channel with you) could float, even outside of the app itself so you would be able to switch through different tabs or apps you're using while still being able to view.

Gather.town is a platform that does this well. When you click out of the app to do work in other browser tabs or platforms, your video appears as a thumbnail and anchors to the edges of your screen. Highly suggest this since I'm interested in co-working sessions.
