HTML5 Outliner Extension

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!

Samuele gg (ID: 000000b00bfe818f) Voted 3 ★ - Updated 03/27/2022 Mi piace la dimensione della finestra, si adatta perfettamente al contenuto dell'indice della pagina, ma putroppo non visualizza l'indice delle pagine e non è possibile aprire sotto-cartelle dei links. ________________________________________ I like the size of the window, it adapts perfectly to the contents of the page index, but unfortunately it does not display the page index and it is not possible to open sub-folders of the links.
