How to get full screen button in other applications on OS X? I want the full screen button in image 2 to appear in the app shown in image 1 (Photoshop). In Chrome there's an option to go full screen, but in Photoshop and Office this does not exist. Is there any way to get it?
Full screen support requires the developer to integrate it in to the app. You can't just 'add' the button to an app.
