Say, "this is how I want the grid to be arranged", and maintain that arrangement over many meetings, with absent people blank and not repacked?
Also, if you are a host/co-host, the order of the "Participants" list keeps shifting. I end up accidentally muting/unmuting people, because their position changed between my moving the cursor over their name, and clicking.
For a service that's probably being marketed a lot at schools, that sounds like a perfect feature for the classroom and you could use it, as well :)
