Usually I have it on the energy display so I can keep an eye on the battery. If I want the outside temp, I'll hold the display button for a few seconds and then it is seven presses back to the energy display.

It would be nice if they extended the top end of the ECO display up to 50 or 60. It's easy to have that display at 41+ on the expressway.
The other nice to have would be adding the missing arrows to show when the engine is charging the battery.
