Hi,

When negotiating a large trade, it can be frustrating to go through the list when the list doesn't match how your magic cards are physically organized.

I propose the following feature:

Allow the contents of the trade window to be sortable by color, or sortable by card type, or sortable by set, or sortable by CMC.

Then it becomes a snap to grab lots of cards from your physical collection.

Rarity would be my preferred sort method.

Should just be sortable by each column that are present (Just like most other views do)
In addition, it would be beneficial to have a Export List so you can do a checklist when going through your cards (and send with the cards so the user quickly can verify all cards are present)
