Keyboard shortcuts to change main screen in a video call

Id like to be able to change the main screen in a video call without the mouse movement, as it opens the lower bar for settings and leave the call.

It would be great to change who shows up with something like a "shift + 1" for the 1st person on the list, and so on.

And just to reinforce the requests, it would be great if the users with muted cameras could show up just with the small pictures.

I hope this features come up soon.
