The OP asked for suggestions. I threw mine in. Rather than just complain about those aspects I dislike, I instead posed a solution that is workable within the current hardware design.
Keep in mind that my purchase decision boiled down to a single question:
"Could I adjust to and tolerate the user-interface in return for the wonderful driving experience"
For me, the car is polarizing. I love the way it handles. Yet the user-interface is nowhere near the same level as the driving experience.
