Xposed Framework has opened the door to a new way to customize our devices without having to cherry-pick and rebuild our favorite ROMs manually. The Framework also gives us a chance to modify stock ROMs with fancy features previously only seen on OEM skins like TouchWiz and Sense.

Many new devices now come with on-screen navigation buttons rather than physical hardware buttons. Prior to Android 4.4 KitKat, this navigation bar took the form of a solid black line at the bottom of the screen. It's not the prettiest part of Android, hence the popularity of Paranoid Android's PIE controls and the emersion of the new immersive mode.

Luckily, you can now easily hide this bar from your screen. All you need is an Xposed module by XDA Senior Member zst123---the same developer who also brought us great features like per-app font control. This particular module allows users to hide the black bar when it isn't needed. You can then bring it back by simply touching the bottom of the screen. Needless to say, you need to have an Xposed Framework installed and your device must be rooted to use this module.

You can grab the newest APK from the module thread. There is also a YouTube video available in the thread where the effect is demoed.
