In the build editor there are only Unordered lists and Ordered lists. I'm in the process of writing a build, and have been using the Unordered list a lot. It occurred to me that it would be nice to have an unordered "Checkbox" list option. That way, someone could print out the build, and have little checkboxes to checkoff as the build progresses. (I know, they can check off the little dots or numbers, but checkboxes would be cooler...)
