It would be great, when viewing a set or deck or collection to be able to sort by at least two different dimensions in a hierarchical fashion. In other words, I organize my cards from each set into rares / mythics and then white, blue, black, red, green, colorless, land, etc, then inside each of those groups by the card's official number in the set. So when I am entering my cards from the selection screen (or just in general), would be great to be able to sort by lets say rarity first and then number in the set second (within rarity). Right now it seems to default to alphabetic after the first sort dimension.
