When there are multiple users on a screen, even 3, you cannot make a specific student larger so that you can see what they are doing. If they are writing on a pape,r and you want to watch them write, the 3rd person gets cut off. If you pull the screen to the right the teacher gets bigger and cuts off the students. This function would be helpful to remote teachers. I had students following directions in a video and was trying to watch to see that they were all completing the steps correctly.
