To move the buttons you will need to add the panel ID skin dictionary which is now is bigger then previously,one of them will move them for each buttons.
I believe this the new panel ID,now just need to know what code moves the main menu button if needed.
Code:

I don't have the beta client or bullroarer client installed and ZI think both clients are offline so I didn't bother to test.
