I would like the card (vertical) size on the Agile Board to be adjustable

My users have expressed their dissatisfaction that the card size on the Agile board consumes more vertical space than is necessary to display the basic information, in most cases. I would like to be able to configure the vertical size of the card, perhaps in terms of the number of lines of text that it will display. This will allow for greater (vertical) density of cards on a board.
