If the hardware allows, it would be nice to blend the Dash - Face - Feet vents as a slider top to bottom (instead of 3 buttons) or slider for each better. Maybe not too common, but wearing sandals here - feet freeze and afraid they'll crack if I hit a Fire Truck (kidding of course). But I can't leave it on feet for more than 10 seconds, even with all three regions on. For the first time, I did wear shoes yesterday (volunteer delivering Dem LB18 signs for David Schapira because Az teachers get nothing), and that was OK on my feet. So it's definitely an open-toe chill phenom. Never thought I'd complain the A/C was too cold in Az! Toes complaining, blood supply is excellent!
