I'd love to see a feature which allows an owner to restrict what a user can see properly. I know I can restrict users to only see orders assigned to them, but it would be much more helpful if a user could only see orders and products from a specific store or stores. This would open up ShipStation to small fulfilment houses who don't have the need for more complex warehouse management programs, as they could set up clients as users who would only be able to see their own stock and orders. This is a huge, and growing market, which currently ShipStation is missing.
