Experiment to be able to change the navigation bar thickness (1/2) 

Use resource overlays to change the 2 dimension navigation_bar_height
and navigation_bar_frame_height to specify how large the navigation bar
is and how large its buttons are (also for width). There are two
overlays: first to slim the navigation bar to 75% and the other to have
floating navigation buttons.
