Split screen camera and desktop
Right now Teams only allows you to view 4 user's cameras full screen, or a screenshare full screen. One of the things my company is looking into accomplishing is being able to allow a meeting attendee to see both the screenshare AND a user camera feed in a split screen. Right now you get one or the other. The ability to minimize/maximize each presenter's window to the size the attendee would like.
Attachment added to show the missing feature.
