Re the choice of haml - you don't have to use haml. That just happens to be what I chose to use, but if you watch the videos you will see that you can create partials with erb files instead.
I intentionally used erb in the videos to try to get this point across, but perhaps I should try to make it more obvious.
Just a quick glitch-in-the-matrix report... in your video about using your own widgets, the state of the shipment was "out for delivery" or something like that. But when you added the widget and refreshed, it showed as a few states behind.
