As a user I want the ability to identify marketplace items (token sets, map sets, adventure modules, etc) that I want to purchase at a later date so that I don't lose track of the ones I want to buy. I often find myself following a twitter or facebook link to a new marketplace offering, thinking I can use that in some upcoming session, and then promptly forgetting about it. Then, when session prep time arrives, I spend 2 hours searching the web and settling for something that is not nearly as good as what hte market place had.
