Sometimes when going through your projects, you have to scroll down or find the search bar to find a specific card you want, and that's just not really cool to do.

 

I would like to turn a card into a list of things, then put any card on that said list! I would be able to open and close the list so that the whole board wouldn't be cramped. This would be perfect for organization, and it makes those "lists" less lame where you get a card, name it, then make it a color cover or smth.
