The Nexus 7 is a huge jump in screen size when coming from a phone, but obviously this tablet is still smaller than some of the major players such as the Nexus 10, Galaxy Tab, etc. One way to squeeze out a little more space is to eliminate the navigation and status bars.
Nelson wrote about the Paranoid Android team’s amazing PIE Controls, which eliminates the two bars while allowing all of the same functionality. But as great as PIE Controls are, it's a somewhat drastic change in the way we control our devices.
Now, we have another option to clear up our home screens.
