This is fantastic! Dirk Eddelbuettel and Jonathan Gilligan have an R package (https://cran.r-project.org/web/packages/tint/vignettes/tintHtmlIntro.html https://cran.r-project.org/web/packages/tint/vignettes/tintH...) that shows footnotes and many other objects in the sidetones. I like that format as well. But it is static and doesn't't change dynamically like this one in the French website you have linked to.
