 For the first, I think the fact that this is now an NPM module sort of goes against it handling this sort of stuff. Google's original concept was basically a plug and play controller that could do everything if you just slam it into the browser and pass it an object. However, in module form, it's expected that you'll most likely be integrating this with an existing application. In that case, you'll probably have pretty specific needs around how you would like to save/load data into your GUI and so it's been left out for now.
