Make sure to set the Backlight Dimmer delay to 0 using the NSTools, so the capacitive touch buttons don't light up.
If you are using the navigation bar, I recommend setting the LCD density to 200 or 190. Edit it with Rom toolbox, or
navigate to /system/build.prop/ro.sf.lcd_density=200 edit it with text editor and reboot.
Always do a backup before flashing. It should work for any JB rom.
To disable navigation bar, reflash the rom, restore the backup or flash disable nav bars.
You are doing this at your own risk.
Its based on Brainmaster's tweaks for android, all thanks goes to him.
Added files, they set dpi to 190 or 200 or disable Nav bars.
