Hide those annoying floating controls for good

As long as the ZoomHider app is running, the Zoom screen sharing controls will be kept hidden, even if you press Esc.
The menubar icon allows you to Pause hiding, Quit the app, and Hide the menubar icon itself.
There's a ⌥ Right Option + Z hotkey to bring back the floating controls when you need them.

How it works?

ZoomHider works by searching for the floating controls window on the screen, and then moving it off screen where it's not visible anymore. This action is done every second to keep the controls hidden at all times.
