I would very much like to be able to adjust the temps with the scroll wheel - the on-screen controls are challenging. My minor variation on @insaneoctane's suggestion would be a short press on the right wheel opens up a scrolling menu (TACC, HVAC, whatever else), and a long press starts Voice Command.
EDIT: @insaneoctane already proposed that on the other thread.
