MarketPress Questions regarding coupons and categories

I have 3 questions:

1. Does Marketpress give me the ability to show (via shortcode or some other way) only products in a certain category on a page?

For example, let's say I have 2 categories of products, category 1 and category 2. I have 2 pages. Page 1 and Page 2. I only want category 1 items to show on page 1 and category 2 items on page 2. Is this possible?

2. The changelog shows coupons based on category. I noticed forum posts asking for this. IS coupon based on category now supported? Coupon per item?

3. Does MarketPress have the ability to show an add-on to a product and/or add an add-on to the cart directly? For instance, Let's say my product is a software product which is what is added to the cart. I want the maintenance cost for the software added as well as a separate item. Is that possible?
