This is really my only issue with v9 - in my case, I preferred to turn off the AC in heat mode to avoid cycling back and forth between AC and heat in the winter, while still leaving everything else on automatic. I can still kind of do it, but have to turn it on auto, turn off AC, set the vents and recycliing manually and then set the scroll wheel to fan and click it to get the fan back to auto. A lot more steps than just hitting auto and turning AC off.
It would be ideal to be able to set auto and then turn off AC *or* heat as required.
