Additional notes **

Build.prop has been heavily modified, a list of some of the common tweaks, some rarer ones. This mostly interacts with the system as far as battery and performance goes.

gps.conf has been changed with the one by Crypted. http://xdaforums.com/showthread.php?t=1880411

Framework change now supports 4-way Advanced Reboot Menu thanks to mikeramsay. http://xdaforums.com/showthread.php?t=2277540

Init.d script sets SDCard to read at 2048 KBps on first boot.

Home Screen button lag can be cured by disabling "Open via the home key" in S Voice. [thanks MikeRamsay]

Now using the 4.2.2 keyboard.

Though there is support in the build.prop for AC!D Audio Mod, they have kindly requested no kangs, so you may flash it independant. Same goes for Bravia Engine 3.

TreveMod_Wifi_Tether has been included thanks to Team Synergy and member TrEvE. http://xdaforums.com/showthread.php?t=1988735

Forced GPU Rendering for all applications by removing a line in /lib/egl/egl.cfg

I recommend KT747 kernel. But this comes with stock kernel. http://xdaforums.com/showthread.php?t=1871946

There may been something very small that I missed. With that said, it is the first release and there will be more to come of this. Thanks.

Not like I've done much here, but please feel free to use this as a base, or to even make changes to. Just make sure you credit the people I have credited, and link to them. Please do NOT credit me. Thanks.

Supremacy v3 script included, thanks to ewmno! http://xdaforums.com/showthread.php?t=1928200
