Very interesting article. I could not understand your point of using vscode for editing notebooks, sounds almost a Sisyphysean effort to me. If you do not like the sluggishness or interface of Jupyter, how about Pluto.jl or Neptune.jl? I use vscode with Julia on its own and really find it great. The other thing, I haven’t tried but I have heard good things about it is using hydrogen with atom editor with Julia as inferior process.
