Are there any plans for the JupyterLab and colab to unfork? Parts of colab seems nice but this feels like a google product that could get pulled at any moment
I see, well you might get a better answer from a Jupyter dev. I use the autoreload extension to automagically pull in my lastest code [1]. It usually works. For your second question you can connect multiple frontends to the same kernel [2].
I suppose each framework has their own shortcomings compared to Shiny. I wonder what key features are missing from those frameworks that would make it a viable option for you?
I wish I could answer this myself but I am somewhat ashamed that I never used Shiny due to R.
I like plotly as well but I couldn't stand the python api nor cufflinks for that matter so I created my own wrapper. It's not fully featured but it handles 90% of the cases I want.
