Overview

Product summary

Review the store description, core capabilities, and common use cases.

This extension is using the HTML5 outline algorithm to create a table of contents.

Should also work well with HTML4 (and older?) pages, that have structured headings.

The table of contents is clickable and tries to highlight the heading/section in question after the jump.

The extension should prove useful to people who find themselves often using online HTML5 outliners.

Comments, bug reports and suggestions much appreciated!

It was quite useless for me due to its position at the addressbar end and it gave no option to change the icons location.

Has its flaws but it's better than nothing. Would be neat if it had an option to see inside Shadow DOM & custom elements.
