Add Shop Type category to Marketpress and add widget to allow global display


I really would like to see a built in ability for Marketpress to display my network of shops by the category they fall into rather than just the products they supply

eg, clothing, shoes, toys, etc.

A simple way to incorporate a selectable list would be great as I find shoppers are looking for a particular item. At the moment, there doesn’t appear to be a way to browse the network of shop in this way.
