Google's official Google Now Launcher is pretty cool, but it's lacking the settings you'd find in Nova and other third-party launchers. There's a way to fix that if you're rooted with Xposed, though. Xposed GEL Settings (or XGELS to its friends) is an app that adds features to GNL so you can have the best of both worlds. This app just hit v2.0 and it's packing some new goodies.
Enhanced integration with Chromecast, including a new "Post-play" experience to easily continue watching at the end of TV episodes.
