There would be a lot of value in being able to pop-out chat windows or call windows to be able to brows teams while still watching a screen share. Similarly with chat I would like to be able to pop-out the windows to be able to simultaneously chat and brows through some of the rest of the teams functionality.

Whole heartedly agree! There is much benefit to having side conversations while on a meeting and it is frustrating to have everything stuck in one window so you can't see multiple things at once (and keeping a little window open in the top left corner doesn't count).

This is one of my top annoyances with Teams - leaving something I am working on to quickly answer a chat and then have to navigate back to where I was.
