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.

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.
