They each add unique features that aren't included in Google Docs-or are vastly better than the built-in feature, enough that it's worth taking a minute to install the add-on. Now, for more tools that don't come built into Google Docs, here are the best add-ons to format text, cite research, add extra content to your documents, automate tasks, and publish your work. Want to include that outline as a table of contents in your document? Just click Insert -> Table of Contents to add it to your document, complete with page numbers and links to the correct sections. Click a heading to jump to that section-or click the x on the right to remove that heading from your outline. Then to navigate your document, click Tools -> Document Outline to see an outline of your headings in the left sidebar. Just write your document, and use Docs' built-in Paragraph Styles to mark your title, headings, and sub-headings. But the best way to do that is Google Docs' new built-in Document Outline tool.
A number of add-ons, including the popular Table of contents and Document Navigator, are designed to find the headings in your document, list them in an outline, and let you jump to the sections in a click.
