Great set of complaints per Jupyter. I think the project is an excellent idea, but it needs to become more mature. I've used it for some prototyping, but it isn't the polished experience you'd like. The web browser is good for looking at the results, but pretty terrible for editing and developing. I'm hoping that with time there will be:

- better front end integration - e.g. a separate vim process connecting/editing cells of a running notebook and updating the browser view on each change

- Fewer bugs and more parity between the python kernel and non-python kernels
