Jeff,
I just checked on this and you are right, once you click on the subcategory, the category list reverts back to the top level categories only instead of staying with the subcategory listing. Not a big surprise considering it reparses the category listings using the new "cat" that you just clicked on and it doesn't have any subcategories to the sub-category you just clicked on. Let me think about that and look at the code tomorrow.

What about multi-level sub-categories? The "hack" that I sent out will only work for one level of sub-category. Do you have multiple levels of sub-categories?

On the issue of empty categories being displayed, the existing system already did that. If you want to shut off a category that doesn't have any products, you can "disable" that category in the admin interface.
