The new release of uc_wishlist, version 0.5, includes bug fixes as well as user interface improvements:

-- added admin options: The administrator can now specify the default title of a wish list, and a token is provided for substituting the user's name. Also, there is an option for allowing anonymous users to create wish lists, which is now by default not allowed.
-- added administrator manage page for listing and deleting wish lists
-- rearranged the wish list page: There are 'add to cart' buttons next to each wish list item. The wish list settings have been moved to the top. Also, I added a notice for users who have not yet entered an address.

The admin settings and manage page are available through store configuration (admin/store/wishlist/settings and admin/store/wishlist/manage). After installing this release, you may need to flush your menu cache to access the new pages.
