Catalog Visibility Options for WooCommerce

Hi, i think Catalog Visibility Options plugin should work based on user role. I mean, we would be able to allow shoping if a user is editor or high.
For now, if a user is registered as subcriber then he/she be able to see the prices.
But with my idea, we can divide the users as visitor (just surf on site) / user (only comment to posts etc…) / buyer (ability to buy products).
