I would like to suggest an improvement to Numista website - at the bottom of each page, you can see, who has the given item for swap but I think it would be great to be able to see, who has the given item in his/her wishlist (as it is common on other websites which helped me make some swaps too). The option “I wish to get this item” is already there so I believe that all it would take is just to make it public, which users have “clicked” on this option for that given item.
Thank you for considering this suggestion in some future update.
