It would be great to have a feature similar to chats where meetings can be popped out so I don't have to "minimize" the meeting to look at my chats.

This would be a huge increase to functionality. Currently, in other platforms (e.g. WebEx, Zoom, GoToMeeting, etc.) all they are is a video/audio conferencing software, you aren't looking at files, responding to chat (not on the same level as you would with Teams), looking at your calendar, responding on Teams channels, etc. I would love the option to respond to chat, channel feeds, uploading documents, etc. without having to minimize the screen during a meeting. Because once minimize you really can't see anything on the screen other then someone is sharing something.
