The Xposed Framework for Marshmallow was just released a few days ago, and we already have a module to use with it. One of the most popular modules ever, GravityBox, has just been released for Marshmallow. Gravity box is pretty much a one stop shop for tweaks and mods on rooted devices. It includes customization options for the status bar, lockscreen, launcher, dialer, quick settings, nav bar, and more! This version doesn't necessary include any new features that we have not seen before. It essentially makes GravityBox compatible with Marshmallow. Head to the link below for the module download.
