new window options for LiveView

With the advent of Sidecar in MacOS, if it great to put the LiveView window on an iPad on set when working on composition. It would be great if you could have ONLY the LiveView frame in a resizable window, so space isn't taken up by the menus. And if it were resizable the window could be shaped vertical or horizontal, since Sidecar does not aloow the iPad to change orientation.

It would also be great if LiveView were zoomable with cameras other than PhaseOne.
