When I send a message to a client and share my screen, I love having a small square of my face in the corner so that the client sees the screenshare and my face.

It'd be nice if, while recording, I could make my video bigger, then minimize it into the corner when I want to share my screen, then maximize it again when I'm done sharing and just want to talk to the client. This would allow for more dynamic messages that benefit from both screenshare and pure video.
