Observing that work is underway with respect to shopping carts (#4500, #4572), I would like to share a related concept: wish lists.

Users can create wish lists containing products of interest to themselves, perhaps to share with others. Alternatively, users can create wish lists containing products to be considered as potential gifts for other recipients. Sharable by URL, online wish lists can enable and/or enhance social, collaborative shopping experiences.

Websites could provide useful features for those users viewing wish lists, e.g., product and product-feature description, explanation, and comparison.
