Is there a way to control what is visible in a Kanban Card, and can we make the cards smaller?

I'd like control what I see in the Kanban Cards. If we have to see everything that is on display, that makes for a very large card, even at the smallest size.

I noticed that a SmartDoc will appear in the Kanban Card, but the Description will not. Having control over the Kanban card could be very creative. I like seeing the SmartDoc info, it helps to get a better grasp on the board overall. The less clicking, the better.

BTW, the Kanban in SmartSuite looks really nice. Very clean.
