view participants at top of screen during presentation
Move the participants to the top of the screen during a presentation and a screen share. Doing this will keep participants from looking down to the bottom of the screen when they are speaking to a person. At least they are looking up which is closer to the camera.

This is important - personal engagement is poor when participants are usually looking below their cameras, so putting faces near the top of the screen (where the camera usually is) can help the meeting work much better.
