Just a thought, and feedback I guess. I have found many users have a pet hate of a link to the page that they are currently on within navigation elements. As long as the current navigation element is clearly highlighted then it is not really an issue for me, however Jacob Nielson has some pretty strong words about it: http://www.useit.com/alertbox/20031110.html #10
If it is an easy fix might be a nice little enhancement for a future release.
