I'm very handy w/ code and since I don't see anything in admin that would allow me to alter the appearance I'm assuming I have to edit some files. I see that Matty did it somehow. What am I supposed to be editing to change the look?

Also, is there a way to deactivate categories rather than delete them, or is there a way to check off a bunch of them to be activated/deactivated/deleted simultaneously? Starting out there are too many categories for somebody who has basically no sites but it's possible that I would want such extensive category mapping if the site got tons of links.

Thanks
