Couple Suggestions for the latest module:
1. When choosing to display the thumbnail/picture for the file, make it clickable so the fullsize image can be displayed in the lightbox.
2. Offer the option to display a shortend description (not in a tooltip).
3. Offer the option of showing the category along with the full path so the category might look like (root>main_category>category). The reason for this is that you might have two categories with the same name but in different tree paths.
