A bit of a theoretical question (sorry) --
I'm confused about how Orchard deals with things like crumbtrails and such, when content has no overall structure. I know there's a module for a crumbtrail, but when content has no specific parent, how does this get managed?
I know there are Lists, and you could conceivably use the list title for a "parent" in the crumbtrail sense. You could use a menu here too. But what if content is a member of more than one list or menu? What becomes its parent?
In a larger sense, is there any facility for an overall content geography (a la http://gadgetopia.com/post/7242)? Any way to organize content into a larger structure?
