This fork prints out the cards in a more card-like manner, suitable for printing out and sticking on a magnet board.
Utility to give you a printable copy of your Trello Board, lists - cards - labels - desc - comments - votes.
This is helpful even when you just want to be able to scan quickly, without having to turn each card over.
You may safely use this for private/proprietary data as all processing is client side - you paste in the JSON exported from your Trello board
