Larger hand mirror

Have a button or feature to expand the hand mirror. the mirror Is very small at the moment so it is hard to see, especially for people with eyesight issues. a feature like a simple expand button or a way to pull on the camera to expand it would be nice. as a workaround I am opening the green camera menu for camera affects a the moment which isn't really what I want to do. I would love for notchnook to have this feature integrated.
