So I used to love the CMD+option+control+8 shortcut to toggle the screen display white/black while using my MacBook at night. I'm realizing now in ML I can't do that anymore, and I have to go all through system preferences to find the option. It's a somewhat silly and useless feature removal such as the removal of "block pop ups" from the Safari menu. Now you have to dig through preferences for Safari to find it. It's unfortunate Apple keeps trying to dumb down the OS... ML is great, but it's unfortunate this is occurring.
