OK, this one's got me stumped. Surely there should be some way to browse all the areas of your site heirarchically? The Navigation menu doesn't seem to contain everything - when I create a page (and fill in the little box that says Add to Navigation), it still doesn't appear in the navigation table.
I've installed a module called navtable, to see if that would help, and it creates some empty blocks that have the same titles as my taxonomies, but the blocks are just empty - title and that's it, no pages showing.
I haven't experimented too extensively with Filestore, but I'm tempted to say it doesn't support this kind of reporting. I'm almost hoping there isn't as I've already hammered out a few hundred lines of code for a module to produces this kind of effect :)
