As a collector, I often want to determine which cards from a specific set I'm missing. For example, I want to know which cards from M11 I have less than two of.

If I filter my own inventory for edition owned: M11, then it shows only the quantities I have of cards from M11. Perfect, except it doesn't show cards that I have zero quantity of. When I have someone else's box of M11 bulk in front of me (or similar) and need to know which cards I lack, I can't get it from this view.

Alternatively, I can use filter the whole MTG inventory for edition printed in: M11. This shows all cards printed in that set, including ones I have zero of. Perfect, except the quantity displayed is the total number of each card I own from any set, not just from M11. If I have two copies of a card from, say, Lorwyn, but zero from M11, it will say two. I have to click on each card's inventory count to see which set my owned quantity came from.

Is there a way I can see just cards from one set, with just the quantity I own of that set, including where I own zero? This would make finishing out collections so much easier. Bonus points if there's a way for me a specify a desired quantity from a given set (i.e. two of each card), and have the number I lack of each card automatically added to my wish list.

This is indeed an feature we'd like to have. Currently thinking of implementing it not within the inventory view, but on a specific edition's page (such as http://deckbox.org/editions/179-magic-2015-clash-pack-promos ).

Agree completely! i always have to go to the card database page

Expanding on this, I'd like to be able to print a list of all the zero quantity cards for a set, so I'll know what i need when at my LGS.

I agree with the original request, this is a very important feature that's currently missing.
Including the ability to print.

I'd also like to be able to apply filters to this view: by rarity, language, color, card type. Especially the language is important to me.
