Suggestion: Beamer-like Slide with (partially grey) TOC at beginning of section

[Schoder]

First of all thanks for developing xaringan. I'm new to it, but I really like it, however I miss one functionality from Latex Beamer in particular. The slides at the beginning of sections and subsections that give the audience some orientation about where we are in the talk (what has been said and what is about to come).

Since I am neither fit in css nor js, I was not able to come up with a solution myself. But I think there might be some other people coming from the Beamer-world that might like something similar in xaringan.

Would be great to know what you think about it. Thanks!

I think that's possible with JS: #217 (comment) I briefly experimented with the idea last year but don't have more time to port it into xaringan: https://github.com/yihui/hugo-prose/blob/16e041908e4d6a59e5c866d641d4787de88ec9b8/static/js/features.js#L144-L193
