Darkroom brightness before restart
Before I restarted my pc I really liked the brightness option that the darkroom provided, after restart I saw what it meant by "darkroom" as in not in a room with little lighting, but a room for processing films and photos. (I suggest you give a warning when you first try to enable it and the key combinations to disable it something like: "This option makes your computer completely red for making films and pictures in a dark shaded room. If you wish to continue keep in mind you can use the key combinations "ALT+END" to end it.")
Could there be an option for the brightness setting that darkroom provides before you restart it? It is currently my favorite option.
