Love the new card view functionality, but it would be great if card view could be used for contact lists as well as dropdown lists. I tested this using a formula in the dropdown list column (=[Contact List]), and it works, but it's not the most ideal solution.
Also, how did you setup the sheet/cards to get what appear to be the totals of the amounts in the cards in each lane in the demo video? Perhaps the sheet that was used in the video demo should be available as a template?
