Summer of Code 2007/proposals

Category Page
I'd nominate working on the Category page to see if there's a way to precalculate the article and subcategory counts, and to make the navigation of long lists of subcategories and articles more like the All Pages special page. The SplitCategoryPage extension I've posted is undoubtedly not up to the code quality spec of the real developers, doesn't do all of the above, and is sloooow. But it might be a nice project for a mentee to work on a similar  functionality with better supervision.
