Received Apple's customer satisfaction survey today for my Apple Watch. Have enjoyed filling it in actually as there's been a lot of suggestions I've wanted to make (although generally I'm a very satisfied customer!). This was one of the final questions and I was interested to hear what other people would answer? My initial instinct was to say how much I want third-party apps to have better access to sensors/hardware but as this is hopefully coming (and will be a big improvement) in watch OS2, it seemed like a waste. Instead I think mine would be sleep tracking. What would your 'one thing' be that isn't upcoming in OS2? Can be any Apple Watch by the way, not just the sport.
