I went back to the product page for Surveyor and FAQs. It says that "Yes. You can re-enter the HTML sitemap wizard to quickly and easily make necessary changes to an HTML sitemap that has already been created by Surveyor." Apparently this does not extend to changing the style, which I know I can change manually in the style sheet but not the point at all. A much more useful feature would be to be able to re-enter the Surveyor interface and change to one of the other preset layouts/designs. It seems like such a fundamental feature, I'm surprised it's not part of the current version. Consider it for the next one.
