It would be hugely helpful if a customer could click directly to a product from their wishlist. As it stands now, they can only either add it to their cart or delete it. If someone else is looking at their wishlist, they would probably like to view what they thinking of purchasing before adding it to their cart.
 
Thanks for considering it!
 

Yes, Metz, that is a normal action and I didn't know it wasn't available.

Interestingly, if you view a friend's wishlist, the products are clickable, but if you are viewing your own, they are not.
