PageNav

PageNav adds a lightweight floating outline to content-heavy web pages so users can preview page structure and jump between sections quickly.

When you open a long article, tutorial, documentation page, or help center page, PageNav adds a subtle outline trigger on the right side of the page. Move your pointer to the trigger to expand the outline panel, preview the page structure, and jump directly to the section you want to read.

Useful for:

- Reading long articles without a built-in table of contents
- Browsing documentation, tutorials, and knowledge base pages
- Finding your current reading position more quickly
- Reducing manual scrolling on content-heavy pages

Key features:

- Automatically scans page headings and builds an outline
- Lightweight floating trigger that stays out of the way
- Expand the panel by hover or click
- Jump to the matching section by selecting an outline item
- Highlights the current section while you scroll
- Supports theme switching
- Supports site-level enable and disable controls

Notes:

- PageNav is designed for content-heavy pages
- It does not guarantee a perfect outline on every website
- Page analysis is performed locally in the browser and does not rely on external servers
