abAutoRig 6.0.3 for Maya (maya script)

First, great setup. Very versatile rig. I understand you were an AM grad, at least I thought I read that somewhere. I would really like to see a jawbone feature added if possible. Just curious if I wanted to, is it a simple thing to add a jawbone and other facial joints to your rig? Knowing the little I do about rigging it would seem a simple thing to go in and add joints to the hierarchy and adding controls. And perhaps that is why its not in the script itself but then I noticed you do have eye joints there too.. so I dunno why the jawbone was neglected. Anyway, I worry that adding my own joints may affect other aspects of your script somewhere. Am I worried over nothing, or is there something I should look out for or avoid?
