Deck-building tools?

It may have been raised already, but what happened to the ability to select cards in a deck and move them to the sideboard?

To build a deck, I go through my inventory and select all cards I want to consider. I move this "pool" to a deck by checking boxes in front of the respective cards and then using the card actions Add to Deck... feature.

Once in the deck, I fine tune what I've included.  I want a quick and simple way to move cards from the deck to the sideboard (and vice versa).

In addition, I'd love to see the ability to build decks from spoiler view in the deck building area. I'd like to be able to modify quantities, add/remove cards, and move cards between the deck and the sideboard.

Long term, I'd love the ability to click and drag the card images to move them between sideboard, main deck, and a "card pool" area.

You've been doing a great job with the site, especially given the amount of change in recent months. Thanks for building the premiere site for MTG inventory management, trading, and commerce.
