Welcome to the forum and enjoy your new NX.
While I understand your problem I find it a non issue because I try to learn the vehicle while stopped. If I don't know something then I don't use it until later. Some of the icons could be clearer and I have not looked at what is behind the switches to make them brighter. This comes form riding a BMW K1600 motorcycle that has a wonder wheel to control various functions. It is very easy to get lost in the new technology of new vehicles and get distracted by switch placement. On any vehicle switches could be placed in better positions.
I am not a real fan of the touch pad but it is better then some other solutions, One of the best is the joy stick on the RX450h.
Take your time and you will learn the vehicle.
