Just a GUI thing here. It would be nice to have the calendar color code the droplets on the app. per zone. Right now when I look at the calendar I know which days have watering events, but if I could have say a blue drop for grass, a green drop for trees, an orange drop for shrubs, I could get a lot more info. with the same screenshot.
I imagine that you can only take that so far since you’ll run out of room, so at some point you may just have to have an icon that indicates that, say a raindrop with a 3+ on top of it if you can only accommodate 3 distinct droplets ?
