The thing that bothers me about notebooks is that they don't seem to be getting better. Splitting the data from the code so that they play nice with revision control should already be implemented by default! Allowing notebooks to also be libraries should be doable. Testing mechanisms on notebooks should be standardised etc. Is anyone working on bridging the gap between notebook sketches and production ready code?
