Thanks Joshua. How could I add category description after title field? I tried modifying above code with multiple different approaches without luck. Any help you could share?

I've updated the code per Bill Erickson's new method, which is cleaner than my first version, see his post.

For outputting the description, you'll want to hook a function where you can output echo term_description( $term_id, $taxonomy ).
