Let's talk about what to do with the right scroll wheel.
By default, the right scroll wheel doesn't do anything (at least for model 3) unless you activate autopilot. There could be many useful functions.
The best function I can think of is to switch between background apps. Another one is to minimize our maximize an open app. For example, if you have the radio up, scrolling down would minimize the radio so so you can see the map.
What do you think?
