Overlay that shows what you're connected to in full-screen mode

Please add an optional overlay, especially for full screen mode. It should show a 15 pixel or so transparent-ish border around the screen in a customizable color (initial color based on host name or Jump Desktop ID) and show the name of the machine you're connected to. Ideally there's a hotkey to turn this on/off. I'm sometimes getting confused to what I'm connected to. :)

Thanks for considering.
