NothingHere
Instantly hide your screen with one hotkey
NothingHere is a lightweight macOS panic button designed to instantly clean up your screen. With a single hotkey, it hides all open windows, mutes any audio playing, and opens a preconfigured document that makes it look like you are working. Guard Mode runs from the menu bar so you are always one key press away from a distraction-free screen. The app is free, open source, and extremely small at around 5.9 MB.
