Hello, I have a NSWindow subclass that resembles the Mac App Store window (the window management buttons moved down a little bit). However, the trackers, which show the X, - and + symbols when you rollover these buttons, stay at the places where they used to be. Is there a way to move them too? I have looked up Google Chrome's source on Github, yet I still can't understand how they did it. (And they use undocumented methods, so I think it will be rejected from the App Store?) Thanks.
