You have no idea. How about making it use modrewrite and put the category and even the sub category into the url as well?
So if I have a this category structure
Action
-D
--Doom 3
---PC
The url would at least have Doom 3 and PC in the url. I would get soo many more hits. Plus in todays day-in-age of others trying to outrank others by simply making better
SEO I think a lot of PP users would benifit from it.
