Deck Changelog

I often mess around with my deckbox decks and lose different states that I liked. I currently manage this by making copies of decks, but it could be better.

This might sound like overkill, but I'd love it if decks had a revision control system. At a minimum, decks could have a changelog showing adds and removes. Even better would be the ability to restore from an old entry in the changelog. The best would allow us to tag different spots in history.
