Table of Contents features

Each is a different shape, not the same box in a different colour. Override any of the four colours or leave them and the design decides.

A design that draws no panel takes your theme's own text colour instead, so it follows a dark site rather than disappearing into it. Every line a design is built from — a panel edge, the ladder's dots, a chip's outline, the reading bar — is held to 3:1 against what it sits on, measured on the rendered page rather than judged by eye.

It works from position rather than from what is on screen, which means it still has an answer in the middle of a long section where no heading is visible at all.

2. 3., nested 1.1.1., roman or alphabetic — and roman and alphabetic alternate by depth the way a real outline does, because six levels of roman numerals is unreadable. The numbers are real text, so they are read aloud and they copy with the list.

Each site keeps its own settings, and a site added to the network later is set up on its own rather than coming up with nothing.

WordPress fetches the whole of wp-admin's CSS and JavaScript again to change one panel; this fetches the panel. The screen you are on is still there while the next one is on its way, and the one you are heading for is usually already in hand — a pointer takes a moment to reach a menu item, and that moment is spent fetching.

Four seconds, and hovering holds it open. No reload, and no scrolling back to find a notice above the header three hundred pixels from the button you just pressed.

So the plugin's other screens are fetched quietly while you read the first one — one at a time, only while the browser is idle, and never on a metered connection. By the time you click a tab the answer has been in memory for seconds.

No two headings on a page get the same one, and a heading that already had a link keeps it, because somebody may have shared it. These are what a search engine uses to offer a jump straight into the right part of your page.

Each save now writes the post's anchors down, and a heading that comes back under a new name keeps the old one working alongside it. It will not guess: a heading replaced outright, or one of two that could each be the rename, is left alone rather than sending a reader somewhere they were not going.

Set the threshold yourself, limit it to the post types and pages you choose, and overrule the whole thing from any single post's editor.

Nothing is saved until you save the post. The classic editor names the bold lines once the post is saved. Nothing changes until you press.

Both take their settings from the plugin unless you override them on the spot, so [toc design="rail" numbering="nested"] tries something on one post without changing anything for the others.

Its [ez-toc], [toc] and [lwptoc] shortcodes and LuckyWP's block show this list in the same place, with their title, heading levels and folding. A post where the old list was switched off stays without one, and links people shared to the old sections still land on the heading. Nothing of the old plugin's is changed, so switching back is one click.

Placed last in the sidebar it stays in view under your sticky header and marks the section being read. It is drawn from the same headings as the list in the post, so the two always match, and a post without a list leaves the sidebar exactly as it was. On wide screens the list in the post can stand aside for it.

An entry for a heading on another page opens that page at the heading and says which page it is on; the entries for the page being read scroll as usual. Every page keeps the heading links it already had, and the editor box counts page by page, so it says what each page will show. The other pages are read without running their shortcodes, and a section a block or a membership shortcode keeps from visitors is not in their list. On for new sites; a site that had the plugin before is offered it.
