Although ListIt isn't designed to be a product catalogue, it's quite useful for
a small number of products. I'm using this setup for one particular website,
however since category descriptions aren't accessible in templates and there's
no way to add more fields to categories, it's impossible for me to output
metadata such as the <h1> and <title> tags.

For example, when someone browses through the category listing, only the
category name can be ouput as the <h1> tag. I would like to be able to create a
new field "SEO Page Heading" where I'd enter text designed for SEO purposes, to
be used instead of the standard category name. I would set this up to act this
way in my template.
