I'm wondering if it's possible to track cards being used in your decks while viewing your collection? I realize there is a similar filter already present in the deckbuilder, but would it be possible to implement this in the collection? Unless there is already a filter like that I'm unaware of. I sort my cards irl similar to how it's sorted in the collection, but tracking down missing cards that might be in many decks is always a hassle irl. It would be very convenient to know which cards are already being used in a deck while viewing the collection to make organizing easier. Would this be something possible to implement on the site if it hasn't been already?
