Limit products to certain Groups
The ability to limit certain products to only be available to be seen by certain Customer Classes (or User Groups as AC calls them) would be a valuable feature. For example, if a certain product is sold to both CONSUMERS and DISTRIBUTORS, two individual products could be created with different SKUs, and one product's info could be tailored towards Consumers and the other one's info tailored towards Distributors. Good functionality would be to have a box on the PRODUCT'S admin page that displayed all User Groups available in the system with checkboxes next to them, allow admin to check ones that you want to display the product to. (Of course have a box that says "Check All Groups" and one that says UNcheck All Groups" as well).
