Would you like just a little bit more screen real estate for your applications? Well, if you are running Mac OS X El Capitan you can now auto hide the menu bar. It works just like auto hide for the Dock, remaining hidden until you move your mouse to the edge of the screen.
To auto hide the menu bar, go to System Preferences | General and check the box next to Automatically hide and show the menu bar.
Now you can resize your application to fill up the entire screen. When you move your mouse to the top edge of the screen, the menu bar will appear.
