Restore screen luminosity when quitting a fullscreen app
I use my desktop with a quite low luminosity because that’s enough for me for reading text. When I use a fullscreen application, it’s either a game, a film, or because I’m displaying photos; I then have to adjust the luminosity of the screen to the activity (all games/films/images do not need the same anyway). But when closing/unfullscreening this application, I would of course like to go back to my usual settings. It would be great if the Shell could do it for me, by saving the luminosity before a fullscreen app is launched/a fullscreening, and restoring it after on close/on unfullscreen.
