Woo Extras: Simple Product Wishlist

The Woo Extras already have a great selection of Woo features, but what I'm really missing is a simple, integrated wishlist. I would like the ability to add a button (either just an icon, or text, or text + icon) to the product archive loop or single product page, as well as via shortcode (so that it can be inserted on a custom location using hooked elements). So that people can add a product to their wishlist with one click. No multiple lists per user, none of that. Just a simple matter of clicking on the wishlist button, and it's added. And clicking on it again, and it's removed. Bonus points if I can choose different button icons depending on whether the product was already added to their wishlist. Furthermore, I would like the contents of these wishlists and the wishlist page to be viewable to the admin. Reason being? If people add something to their wishlist, I may be able to entice them with a personalized discount to actually buy it. Especially when it's under the countdown timer. That way, they may be more likely to buy the product quickly instead of having it waste away in their wishlist forever. The social share widget is also great in conjunction with wishlists, as this could drive more traffic to the site. It would be great if this wishlist was also available to any visitor, not just members.
