Xposed Framework Modules are all the rage in Root Mods for your device. They can bring you all the favorite features from the roms you love without having to actually go through the hassle of unlocking your bootloader, flashing recovery, and installing a rom. You only need root and the Xposed framework to apply pretty much any mod you like to your device. Omni Rom has become one of the most popular roms around for multiple devices lately, and one of it's top features is now available for any device with root via the new Xposed Framework module "XMultiWindow" by dev "LovewuChin".
