missing order of lectures on the website (and possibly time estimate)
- Currently, lectures are not sorted in the index page.
- Call-outs (e.g., tips, warnings) are collapsible: https://quarto.org/docs/authoring/callouts.html#callout-types
- We could use them to display a table of lectures and time estimate
- Regarding time estimate, quarto can automatically compute reading time based on the number of words, this could be an interesting proxy. See https://quarto.org/docs/websites/website-listings.html#listing-fields
