 # revealjs.ids (development version)
 
+- Slides titled "Overview" or "Überblick" are now automatically turned into a table of contents (ported from the old Google Docs slide workflow): their body content is replaced at presentation time with a hierarchical, clickable list of all `#`/`##` slide headings.
+
 - Speaker notes (`::: notes`) and timing comments placed before the first heading are now attached to the title slide instead of ending up on a separate empty phantom slide after it, so the title itself can have a time budget and a welcome note (shown in the speaker view and the mobile notes overlay, and included in `slide_timing()` and the pacing timer).
 
 - Disable reveal.js' automatic scroll view on narrow screens (`scrollActivationWidth: 0`): when a phone activated scroll view during load, it restructured the slides DOM and the slides menu degenerated to italic "Slide 1..N" fallback entries. Phones now get the regular swipeable slide view, where menu, speaker notes overlay, and pacing timer work as usual. Re-enable with `reveal_options: list(scrollActivationWidth = 600)` or force scroll view with `view: "scroll"`.

+The TOC is generated when the presentation is opened, so it always reflects the deck it is part of. Slides without a heading and the title slide are left out.
