Baxter,

Last weeks we are working on new version 4.11, which will include the feature you need. The beta version is already available on Download page: [url]http://www.firetongue.com/download.shtml[/url]

In short, there is a pair of new fields for genres. Moving from categories to genres should be easy: if you already entered categories, they will be ported to genres once you install new version. And you can browse content by genres as well.
