Feature request in Quarto vignettes: code filenames

[Nenuial]

If I am not mistaken, code filename are currently not implemented in the rendering of Quarto vignettes.

I believe this would be a really nice feature to have. Showing the filename makes documenting configuration for example, much more explicit and readable.

It would be helpful to add an example of the utility of these changes in the quarto features vignette (vignettes/test/quarto-features.qmd).

Of course! I added the example as requested.
