It would be very useful if a pushbutton that I place on the dashboard had some sort of feedback that it was pushed. That is, on many UIs a button has two graphics one for "normal" and one for "being pushed". Thus you get the illusion of a button pushed when you click on it. Just a dot or any kind of feedback while pushing would be ok though.
And while I'm at it, I'd like to suggest that any user interaction with the dashboard (a button push is an example) should (optionally?) cause a refresh in a few seconds. Use case example: I have several push buttons for different 'scenes' in my office. One of devices displayed on the dashboard is the thermostat. I'd like to be able to see that in the "preheat" scene the thermostat has turned on, and in the "overnight" scene it has turned off. Yeah, yeah, it is not that hard to manually refresh, but combined with the lack of feedback from a button, it is just a bit non-intuitive.
Thanks for a great product!
