Trading opportunities are currently sorted only by the trade value. For a variety of reasons, this isn't always helpful. For example, some cards have no listed trade value (e.g. Nexus of Fate). It would be helpful to be able to sort this list by the number of matches (either haves, wants, or both).

There are also a lot of cards that are foil-only but that people don't always list as foil-only: Buy-a-box cards, FNM cards, masterpieces, convention promos, planeswalker deck planeswalkers, judge promos, etc. It would be helpful if the Trading opportunities page would match these correctly, e.g. if I want a foil Dovin Architect of Law and someone has listed a nonfoil Dovin Architect of Law on their have list, the Trading opportunities page should treat these as a match.
