title: Re-enabling the XCode 4 "show this screen when Xcode starts" checkbox.
body: <p>I've managed to uncheck the Xcode 4 'show this screen when Xcode starts' checkbox and I want it back again. How is this achieved? I can't see anything in user prefs, nor is there any reference to it in the Xcode 4 documentation - aside from 'starting a new project'. Further, there don't seem to be any existing questions anywhere on Google. If anyone knows where the re-enable checkbox is - please tell me. Thanks again.
