One of the WP sites I support was asking me about a way to handle categories that apparently is not supported in the current version (or any previous version either). Currently the categories which show up on the right hand side menu bring you to the entire base of articles if you click on them. My client suggested that it would be nice (and I fully agree) that it would be good to be able to expand a given category title and select an individual article from under that category.
for example: say you have 3 articles in a given category and currently when you click on the category name under the categories section on the right hand navigation menu in WP, it will load all articles for that category. What we would like to see is an addition that would allow us to pick an individual article from a category. (I envision this as a expandable link).
Feel free to contact me if I can be of further assistance or you need clarification of what it is that I am trying to convey.
