I was not able to make this extension work with jupyterlab 3.0.0 and after installing the extension using `pip install jupyterlab_vim`. I checked that the extension was activated ("enabled OK")...

Thanks for implementing that. I see that SymPy is also available in Julia. I don't know what is the preferred symbolic package. Do you use some package to deal with...

I see. Yeah, the indexing and formal sums seems very powerful (I have not used this feature yet myself).
