Sort of like many popular trading card decks have the cards rules right on the card. You can put them in an image, but that's a lot harder than typing into the card itself. Player editible cards would allow players to take notes on certain cards for various reasons. I would also like a hidden DM notes for cards. For example I give a player a card for a "Spear and Magic Helmet" and the GM info has information about lightning charges left. I'd also like a setting to display the card names at the top of the card when it's face up.
