 # 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 clickable list of all `#` chapter headings. Adding `{data-overview-subheadings=true}` to the heading also includes the `##` sub-headings, laid out in two columns.
+- 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 clickable list of all `#` chapter headings. Adding `{data-overview-subheadings=true}` to the heading also includes the `##` sub-headings, laid out in two columns. References and appendix chapters (References/Literatur/Literaturverzeichnis/Appendix/Anhang) are excluded, together with their sub-slides.
 
 - 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).
