Shopp was easy to customize. Having more experience and education in design I was quite easily able to customize the Shopp templates. I modified the Shopp landing page to show the categories and not all the products. When a category was selected you then see the products in that category. I displayed the category image and title on the product listing page to indicate what category the products where listed under using the simple php calls. For the product page I used the same php calls to show the category the product was listed under. Using your snippets from your documentation I was able to add certain features for products listed under a certain category.
