Enable/disable do not disturb on screenshare
Now, that the shell knows, when something is screesharing, it would be neat, to also toggle your "do not disturb", so that you don't get notifications, while sharing your screen.
One thing that would make this more sophisticated, would be to be able to have different behavior between full desktop share and window/tab share. The latter ones, probably could leave the DND untouched. I'm unsure if shell has these kind of informations.
