Not a dev, but I am a fan of the Dock. It's a great feature, and I use it a few times a day, most every day.
The only change I want is to add Contacts to it. Streamlined for the Watch, it would have two buttons— Call and Message. I clear my Message queue regularly, so if there isn't a recent text, it's not convenient to start one. Siri works, but sometimes you don't want to be overheard when advising "Eagle has left the nest and is Oscar Mike. Repeat..."
