Chrome's Warn Before Quitting

It may not be nearly as important once Lion gives us all instant-resume for our apps, but the latest version of Google Chrome (v12) adds a delightful feature called Warn Before Quitting. Set it in the File menu, and from then on Chrome will ignore a passing ⌘-Q but will quit if you hold down the key combo. No more accidental quitting when you were aiming for a ⌘-W to close a window!
