Other than the cards, there are several areas on the screen where you can swipe. As many people are aware, pressing "Navigation" and swiping down will quickly navigate you to home (unless you are already near home in which case it will navigate to your work address). Today I accidentally learned another two. Pressing on the temperature and swiping left or right will quickly change the temperature - this is much faster and easier then trying to find the little up and down arrows. The same works with the volume control (of course, it is still easier on the steering wheel). I am now pressing various areas to see if swiping does anything else. So far I have not found other functions.
