Add a clickable table of contents, automatic heading numbers, figure and table numbers, and cross-references to Google Docs™ — and renumber everything with one click after you edit. Your document stays yours. Reads only the document you have open. It changes the document only when you press a button that adds or removes numbers, captions, references or the list of figures, and its content is not sent anywhere. It asks for one Google Docs™ permission, "documents.currentonly", which covers only the document you have open (not your other files or your Google Drive™), plus the permission to show its sidebar. Free - Contents sidebar with jump-to-heading - Heading numbers 1 / 1.1 / 1.1.1, renumber and remove - Figure and table numbers, up to 20, renumber and remove - No watermark Paid ($19, one-time) - Every heading number format: 第1章 / 第1節, I / A / 1, "1.", "(1)" - No limit on figure and table numbers, with chapter numbers (Figure 2-3) - Cross-references that follow renumbering - List of figures and tables with page numbers The only outside service the add-on ever contacts is Gumroad, and only to check a license key: your browser sends only the license key and the product ID — nothing about you or your files. How to use Open a file, then choose Extensions > Table of Contents & Numbering > Open contents & numbering. In the sidebar, click a heading to jump to it, press "Number headings" to number them, or select an inline image or a table and press "Add to selection". Every addition has a matching Remove button. If you are signed in to more than one Google account and the sidebar does not load, open the file in a window signed in to only one account.
