Virtual Tabs

Notes with URLs that aren't currently open appear as "virtual tabs" — click to open the URL in a new web viewer.

Paired Opening

Domain Grouping

See all notes from the same domain at a glance. Sort by name, count, or recency.

Frequently Asked Questions

How does the plugin find my web notes?

The plugin looks for notes with a URL property (default: source) in the frontmatter. You can customize which properties to search in the settings.

Why doesn't my note appear in the sidebar?

Make sure your note has a URL property in its frontmatter that matches the web page URL. Check Settings → Web Sidecar → URL property fields.
