I'm a heavy Emacs user. However, on my Mac, if I switch Emacs to fullscreen mode, it will use Mountain Lion's fullscreen style, which places Emacs on another desktop. In this fullscreen mode, the 2 top lines are wasted since I cannot use them for displaying the Emacs buffer (you can see in the picture below). Also, the animation when I change desktop is annoying.
I wonder if there is any solution to force Emacs not use Mountain Lion's fullscreen style. I just want a maximize displaying area (hide the menu bar, hide the title bar,...) like when I playing video in fullscreen with VLC 1.x
