Yep, I have actually thought about this, and it is one of the most common
comments I have gotten. I would love to do this, and have actually played
around with it. The problem is that it is incredibly inefficient for the
code/database. Basically, each time I display a category, or a list of
categories with their link count next to it, I would have to traverse the
entire category table to find the very bottom for each category in question.
Then I would have to climb the category tree back up counting and/or
displaying along the way. This is a healthy load on the database and user
load times.
That being said, I am working on some alternate methods of displaying all
links (not all by category, simply all) which might help some people out.
More info on this soon.

I made a tweak this morning. The category sidebar now looks like this:
SubCategory Name (link count in this subCat)
SubCats: (Number of subcats under that particular subcat)
Check it out and let me know if that helps. And keep the suggestions coming!
