I've just released 2.1 version. The main improvement is the addition of a button dedicated to Away state toggle. ericg301 should be happy about this
Other than that, I fixed a bug where the widget, upon opening, would sometimes be blank for a second or two, and then appear. So now it's possible to start adjusting right as the notification center opens, under all circumstances, as advertised.
Another bug was that the setting for the small modular complication display type would be ignored, and it would reset back to showing the target temperature. While this is now fixed, you may need to go to watch / app settings, unselect the wanted option, and then re-select it, after installing this update, so that the setting would stick. Sorry about this.
Lastly, I've ironed out a few UI rendering quirks, like the one you can see on gwhizkids's screenshot above, where the line cuts straight through the text.
For the next release, my plan is to add the HVAC mode selection to the widget, but I'm listening to any ideas, as usual.
