HeadingsMap Extension

The extension generates a document map or index of any web document structured with headings, allowing direct access to content by clicking on any of its items. It now also displays the HTML5 outline.
Although the extension was initially meant to assist web developers, consultants, and accessibility auditors, it turned to be useful for many users, facilitating the reading and navigation in long structured pages

Features:
* Lists headings with optional information about their levels and any breaks in the correct hierarchical structure.
* Lists sections with header information, including optional details about structural errors.
* Provides information from the main document and documents within frames, featuring a document selector when multiple documents are present.
* Clicking on headers scrolls the document to the corresponding position and highlights it.
* Detects changes in the DOM and updates content as necessary, with an option for manual refresh.
* Allows collapsing of the header list by levels.
* Optional HTML5 Outline test.
* CSS outline for identifying headers or sections when clicking the tree.
* Does not display hidden headers or sections (hidden from assistive technologies).
* If a header or section is an anchor, the link in the results points to it. This is useful for copying directly from the tree using the browser's contextual menu. Optionally, it shows anchor-links that copy the link to the clipboard when clicked.
* Two themes available.

Erin Lynch (ID: 00000035e320a936) Voted 5 ★ - Updated 04/30/2023 This is a great app. I'm maybe not the target user, but I've found this really helpful for studying, in particular reading textbooks and research papers online and navigating huge amounts of complex info without getting lost. It's a huge help. I like copying an article's structure (from HeadingsMap) into my notes (in Notion) and then filling in the subheadings with the most relevant bits/my actual notes. Here's where my only issue arises. Every line copies in the heading number before it, so it's like '1Introduction, 1Argument 1, 1Argument 2' which is quite annoying. Anyone know how to fix this? Thanks.

Leon Niceday (ID: 00000085ed7df105) Voted 5 ★ - Updated 04/20/2023 Impressive. Robust and high quality. Perhaps one feature I'd wish is ability to selectively collapse/expand all headings of a certain level/depth. Or, ability to only show h1-s initially, then click a button to expand the rest, or one level at a time.
