I was going to start a wish for this but I'll bounce it around you folk first.

there are two display states: Info and visual. Info has two sub-states: now and next, track info list. Visual has three states: Visual only (info off), info on, transient info.

In the car at least I'd like to be able to switch between the two main states by using the down button on the front panel then the remote is used to switch between the sub-states therein. ie, as per when you start the car. the info screen comes up and you can hold the button for the visual, but it comes up in the last mode
I find that having to cycle through several info screens a bit cumbersome while driving.

I haven't yet thought how it should react when on AC power.
