If you hack or flash ROMs and various "stuff" to your Android phone, you know about ClockworkMod recovery. +Nathan Grebowiec has just taken it a step further, and built an unofficial version for the Galaxy Nexus (both versions) that uses the capacitive buttons while inside recovery. It still does all the same functions as the original, and you can even restore backups made from previous versions, but now you can do it without using the volume keys.
Is it really necessary? Nope. But it's cool, and how open-source works. Nathan took the source code and modified it (and we're sure Nathan will share the source code once it's out of "alpha") to do something he wanted or needed. Seems like it works rather well, so if you're interested, grab it at the link below.
