The wishlist page has finally been updated and rolled back from the poor 2.0 version of the integrated app that we were forced to update to when we updated the site infrastructure to shopify 2.0
The old version 1.0 page view version has been restored and a stock filter option has been added to filter by in stock or out of stock products. Additionally all lists created by customers under the 2.0 system have been rolled together into a single list. There is no way to do multiple lists on the version 1.0 page view setup, so they've been combined into a single list.
Everyone using the wishlist should clear the site cookies and clear your browser cache if you experience any loading problems.
