When you are creating a hierarchy of pages, it would be quite useful to have a {subpages} option similar to {toc} that lists the subpages of the current page (perhaps in a ul, or other list form)
If you could do {subpages 1} you could create just the 'next level of detail' where {subpages 1-} or some such could generate a site map type thing that would stay up to date.
