I think it would be very intersting. If can set custom position.
And size. In CloudApp you can make your camera full screen or change the circle into 3 different sizes. Really great feature!
Also, an option to flip the webcam 180 degrees could be a great add on, especially when your face moves to the other 50% of the screen to go to the opposite corner, you don’t want your face to be looking outside of the computer screen.
EDIT: As of December 2022, all this is now doable with the macOS app
ability to make it what size we want and position it where we want !!
