Version 0.6 includes bug fixes as well as user interface improvements:

-- on the wish list page, 'add to cart' buttons will add item even if the quantity has not been set
-- fixed bug causing error message about items from multiple wish lists
-- fixed bug that caused wish list items to not include shippable parameter (any items added to a wish list before this fix will not be marked as shippable. so you have to disable 'Hide shipping information when possible for carts with no shippable items.' in the checkout settings.)
-- added redirection back to page where user is prompted to login or register
-- added 'create or manage my wish list' link to search page
-- added CSS file for custom styles on wish list search page

Let me know how it works. Hope you enjoy.
