Been searching awhile now and came across this.
this is going to add a back button home button and search button your screen. Always will be there and looks exactly like the new droid razr phones.

**this will disable your menu home back and search light up buttons and there is no way back unless you completely delete the rom**

Works on ics build rom Icarus. Not tested on others so flash at your own risk!
