In the library panel, find the Segmented button, click on the classes. Find NSObject or any other class that you would like to subclass. Right-click and "New Subclass ...", name it something useful in the pop-up menu, for example, the controller / AppController. Find the new class in the class list. Now add all your actions / exits to the bottom of the library panel. Thanks to the convolution, I would never have found this. (Just thought I would expand on this tip).
