Breadcrumb Widget for pages not in navigation

Just a suggestion to make the breadcrumb widget work even if the page is not in navigation. IE if the page is in a child directory of Stuff then allow the breadcrumb widgets to work there would be great. We have pages that we do not want in navigation but want them to exist and have people be able to navigate their way away from them such as the 404 error page. From that page the breadcrumbs don’t work and since we don’t want it in navigation we are stuck with a customized solution.
