Extending the SAS kernel to collapse the log like Quarto can do with code chunks

[bvancil]

I am eager to use the SAS kernel in conjunction with Quarto, since I can write using a Markdown-like syntax, to provide more stylized SAS-generated reports for my end users. Quarto has an option to code-fold: true, i.e. hide the code cells behind a toggle. It inspired me whether this would be a great option to display the log above the lst output, possibly with an indicator of the number of errors, warnings, and info statements, like SAS Studio does. This would be useful not just for Quarto but for those using Jupyter notebooks. I'd be interested in working on this feature but would need some guidance on how to proceed. If the SAS kernel had this feature, would you prefer it be turned on via some feature flag or implemented as a cell magic (maybe %%foldLog true?) like %showLog is now? I was tending toward a feature flag at the beginning of the notebook because I'd want to use it for nearly every cell, but I can see that one may want to override it at times.

I wanted to gauge interest before working on it. If others are interested in this feature, would someone be willing to mentor me in developing it? Thanks for your consideration!
