R notebooks are the bees knees and frankly I'm surprised Jupyter hasn't borrowed more from them. It's so much easier being in plain-text until render time, and the output is easier to manage because you can trivially decide what chunks you want to echo, evaluate, plot at 2x size...etc without any change to the interactive usage. Not to mention you get to retain your nice IDE features like good code-completion, doc lookup, version control... I am excited for Jupyter Lab and it's a step in the right direction. But it feels a little bit like they're reinventing the wheel with some of this stuff. I would gladly pay money for a python copy of the R ecosystem with RStudio, R markdown, R notebooks, where everything just works great by default.
