links.php

Greetings.. I really dig the link manager. It’s very cool. I have one request…
I would like to be able to display the category names, either by editing the configuration files and toggling it on… or by directly modifying links.php. For example, I’d like it to display in my menu like..
Category 1
-Link 1
-Link 2
Category 2
-Link 1
-Link 1
Any suggestions on how I might acomplish this would be great. Regards,
Jeff
