The chat screen is always attached to the video screen. While I am sharing my powerpoint on the desktop, I have to exit the presentation so I can go back to the main screen. Is there a feature that allows us to undock the chat screen so that it can hover above your screenshare? I'd like to be able to chat and present at the same time; this is very important in online classroom instruction. I know Zoom has this feature. If you do too, where is it coz I can't find it.
