This patch allows you to capture photos or videos by pressing on the volume rocker instead of using the on-screen buttons. Press Vol+ to snap photo, and Vol- to record video. Press Vol- again after you begin recording to stop recording. It's simple as that.
Shout-out to eblade for bringing this up on Twitter.
BTW, I had a pain generating the patch for this. Originally this patched three files, but I can't figure out how to include a file that doesn't already exist. Then appending the new code to the end always gets rejected for no apparent reason, so now it's just sandwiched between the leading comment and the camera app code. Not pretty, but that's the only way I could get the patch to apply.
