I was so frustrated when I switched from Snow Leopard to Lion and found that the "Save As..." menu item had vanished! I used that all the time to dupe a file and create another regardless of application, but suddenly it didn't work. Now I'm running OS X 10.8 and I still can't restore it to my "File" menu. Yes, I know that if I hold down the Option key it magically shows up, but jeez, is there a way to restore "Save As...", even third party software?
