I am thoroughly enjoying using the screen real estate that comes with 1920x1200 for web browsing, but when I'm using Aperture or FCP I'd prefer to be in Retina mode. I know I can switch between them from system preferences, but it would be easier just to have a toggle switch. Next to the bluetooth and wireless toggles. Does apple allow preferences to be changed with an app? If so, anyone else think this is a good idea? Or better, anybody an interested dev?
