The script button is not new, it has been around in previous versions for years and everyone should have already familiarize themselves with it. The neat thing I like about 2012 SSMS that is not in previous versions is the ability now to see both the Registered Servers Window and the Object Explorer Window both docked on the left in SSMS at the same time. No more jumping through hoops to make this happen. Yeaaaaaa! This was always a pain tabbing back and forth or hitting F8 and Ctrl+Alt+G. This may sound trivial, but sometimes its the little things that can make your SQL life much more convenient. :-D
