Ok got gravity box installed.. it does have an option called "advanced reboot menu".. when selected it automatically enables another reboot confirmation popup with additional boot options listed as reboot, safemode, recovery, or bootloader.. when this is enabled it also allows you to disable the stock confirmation popup.. But there is no way to disable reboot confirmation all together so basically you are just swapping stock reboot conformation for a more advanced one.. which I have done .. Overall the gravity box module is pretty cool tho.. thanks for sharing.
