Add an option that allows to set a custom hotkey for disabling the injection without having to focus the app window first

It's more convenient, especially when playing a game where the standard keyboard layout is also convenient for other game functions. Having the ability to switch the injection off & on would come very handy in this case.

depending on your desktop environment, you can map a shortcut to input-remapper-control --command stop-all or something like that.

In KDE, there is the "Shortcut" settings pane in the "System Settings" for that
