GravityBox [MM]

with a tweak, box to turn their vanilla AOSP ROM into custom ROMs.
 
As you can imagine, users will need to be root on their phones if they want to use GravityBox [MM], and, since this is a Xposed module, it will also need the Xposed framework. The advantage of using this particular module is that users don’t need to flash their devices in order to make it work.
 
If you choose to use GravityBox [MM] you should expect quite a few interesting features, including QuickSettings tile management with additional tiles and tile reordering, CyanogenMod Pie Controls, an improved desktop with semi-immersive and immersive modes, various tweaks regarding the lock screen, status bar, navigation, power, hardware, dialer, smart radio, notification control, and much more.
 
Please keep in mind that the module only supports AOSP devices running vanilla Android 6.0.
