very nice theme. I like the idea of list categories on left side.
also becase there is no some sort of clickstream its hard to navigate from categories or details view. and in details view it doesnt say in what category u r.
P.S. there is little bug in the template, in one table uses width="75%" that makes not very nice "problem" effect on screen with resolution over 800x600. width="768" would fix it.
