How does the Auto Table of Contents (from Headings) work?

Detect headings in a PDF (by font size — text rendered noticeably larger than body) and prepend a Table of Contents page with dot-leader entries showing each heading and its page number. Different from Auto-Bookmark from Headings (which adds bookmarks to the navigation panel) — this tool produces a printed TOC page that's part of the document itself, the way books do it. Useful for adding a TOC to a long PDF report or an exported manuscript before sharing or printing.

Frequently asked

They're not — the new TOC page becomes page 1, so heading-on-original-page-N becomes page-N+1 in the new file. The TOC accounts for this.
