It's a promising module, but it is a pain to manually have to select what books, menus and categories should show. Besides, it is not good that each time somebody adds a category on the site the webmaster has to go to the Site Map settings and add it to the site map...
OK, I know that sometimes it may be handy to be able to select which of these should not appear in the sitemap. But
But it definitely should be possible to have a checkbox for each of these saying 'add all automatically' to automatically included all blogs, etc.
