Hey Deep, thank you for making such an attractive UI to this and a blog post to introduce it!

I'd like to add some thoughts about the API that this requires more boilerplate than I want. Is it possible to simplify this API so that user's do not need to manually register each context in both the provider and the consumer? Getting react-context-devtool as good or better than redux will require getting the API of this extension just as easy.
