This module adds a new L-styled home button to your navigation bar, which doubles as a battery indicator.

This module is fully configurable, the settings app is hidden from the launcher, access it by going into Xposed, tapping modules, then tapping the module itself.
This should work with most ROMs on most devices (HTC, Sony, Nexus devices, AOSP, CM, PA, Omni etc). LG devices are currently unsupported on stock ROMs. Patches welcome since I can't get my hands on an LG device.
