Pop opens several windows, like for example the main window, screen share window and others.

It would be nice to use different window colors to indicate which window is for which functionality.

I found myself lost looking for the right window several times.

Alternative:

Put everything into one window with intuitive UX to align the elements beneath / below each other or easily switch them.

https://room.sh/ dows. Many Videochat tools are lacking a good UX for these elements.

Multi-window is OK but please review the UX :)
