Idea: Show column for available count in your friends' tradelists

When building/editing a deck, I love being able to see the Inventory, Wishlist, and Deck count columns on the left, so I know what I have and what I need.  I think it would be great to have an *optional* non-editable column that would show the count in your friends' tradelists, so you know what is conveniently available for you to get from a deckbox friend without having to click on every card.

It would also be nice to have that same friends' tradelist count column in your wishlist as well.
