This is great and I've been wanting to try out Docker for a while. Here's some feedback: 1) I had to delete my existing host-only networks 2) Images could be pre-populated with popular images so you're only a click away from getting started with an app. As a first-time docker user I don't have any of that stuff lying around. Edited to add: 3) A progress indicator would be great creating/starting apps and images 4) am I supposed to install docker separately to access the command line tools?
