Okay I tried it out... it's pretty funky. I was expecting to get a fully featured Jupyter notebook, but the Interactive tab is more like a REPL because the "cells" are immutable. You can re-run the cells, which is something. It seems like it's somewhere between a REPL and a notebook. Though interesting, this tool is unsatisfactory for my workflow - if it was I would have just stopped at using an IPython REPL (not being able to freely edit and manipulate cells is a deal-breaker for me).
