Ok, so speaking of things people emailed me about, I've also written up a quick wiki describing the common functions of the TouchShield.
I made the whole reference completely wikiable, so anyone can chime in and contribute, or add functions they find useful. I don't like it when wiki's are set up by people with lots of complicated user permissions and passwords, and anyway I think that defeats the whole purpose of a wiki anyway. I hope it's helpful!
You can check out the function reference over here.
