I agree with making the manual activation easier. It doesn't really need to be oriented toward winterization, though. The first time I used the app, I expected to be able to turn on a zone from the cards in the Zone section or from an individual zone's Zone Details screen with a single tap of a play button or something similar. Alternatively, you could alter the remote screen to show a list of zones up front so I could just tap a zone to start/stop it immediately without having to select it in the drop down and adjust the watering duration on the circular dial. That's just too many taps to do something as simple as turning on specific zones while I'm just trying to evaluate the spray pattern, locate the heads to place markers before aeration, etc.
