Just a couple comments on the Directory Resource:
It would be nice if the Directory Resource listed files more like the Resources page than the Files page. For one, as mentioned below by Sarah, the files popup in a window sans toolbar.
And another, although it is nice to have the file size shown, I really do not want my users to see the date last modified. Alas, I have gone back to simply adding an html resource and adding my file links to the page for my "Directory".
