I found that I was using the wheel warmer button way more than I through I would. It's located right in middle of a cluster on the central console, in an awkward place to look at (right next to my hips in a blind spot).
I devised a nice and cheap fix for this UI problem that wouldn't be applicable on a touch screen: I put a googly eye sticker on it.
Better tactile feedback, no loss of function, and more whimsy in my otherwise boring car.
