Owned cards vs cards in decks

I would like a few options regarding my owned copies vs. copies in decks

• when I hover over a card in my decklist, i would like to see how many copies of that card (in whichever version) I have and how many are in decks. That way I know whether the card is available. Preferably the deck it is in since I keep track of my retired decks and decks to be built

• basically the same functionality for EDHrec cards so I know whether to add them or not

• some form of functionality to the EDHrec page, such as deck types, sets, new cards only (maybe based on the newest cards in the set)
