In presenter mode, show where the camera circle is located. Also allow moving it.

Is your feature request related to a problem? Please describe.

When I am presenting, I don't know if the camera circle is hiding important content. I am only looking at presenter mode.

Describe the solution you'd like

In order of importance:

• in presenter mode, show a filled-in black circle where the camera is currently positioned, so you can see what it's covering
• in presenter mode, allow moving that circle to reposition the camera
• allow turning the camera on and off from presenter mode (maybe browser APIs will not allow this, in which case it can be skipped)
• In presenter mode, allow toggling this camera preview between: black circle (maybe choose the color/opacity/outline/fill too) or actually seeing yourself in the camera (again, this might not be possible in browsers)

Describe alternatives you've considered

I could have both windows visible: presenter mode, and the window that I'm presenting to the audience. This is too distracting to give a presentation, and hard to keep checking on the second window if the camera circle is blocking anything.
