It would be great if you could add some options to make card views easier to print/save to pdf. Right now if you try to print the card view the cards will be split over several pages or something like that.
Just the feature of having the cards adapt to the page and the option of choosing how many cards to print per page would make the card view much more powerful. This would essentially be a super easy to use merge for business cards, name tags, address cards, flash cards, bios, product info etc.
