Foren / Cotonti / Development / Siena shop plugin - wishlist?

I have created a plugin that is similar to a shop. You can transform a list category to the place where users can select and add pages/products to a basket-like page. In my case, it's just used to print a pdf of a marketing offer and send it to client by mail (the website consists of product pages)

So far it features:

- a basket (session and mysql based)
- a personalized PDF print of summary of items
- extra fields for "orders" in basket (you can add the fields like "Client", "Address" etc.)
- archiving, deleting, copying, "orders".
- Sending the pdf file to a given email address

Maybe you'd like me to transform it into a shop plugin? If yes, what features would you expect?
