To those using GravityBox, I would recommend using Xblast Tools instead.
Gravity box assumes AOSP, or very close to AOSP. Also, due to the way GravityBox is written, all the scripts are added to your ROM by default, even the ones you don't necessarily want to use or because you already have another module performing something that GravityBox does. This makes the chances of your ROM having a "script war" very high and you could end up with a poor-performing ROM, or, at worst, a bootloop needing a reflash.
GravityBox is a fantastic module, in the right environment, I'm just not sure that CyanFox is the right one.
