I played around a while ago with the TOC in the Sidepanel and got this working:

# Table of Contents for the Sidepanel

**_Because scrolling through a 200-heading page to find the right section is nobody's idea of a good time._**

A live, collapsible **Table of Contents** that pins itself to the right-hand side (customizable) of your editor and actually keeps up with what you're doing. It folds and unfolds sections in the document as you navigate the tree.

TRY IT OUT 👉 ${widgets.commandButton("Toggle Table of Contents","Toggle TOC in Sidepanel")}

## Core Features

* **Live Heading Tree:** Renders all headings from the current page, auto-refreshing on page load
* **Undirectional Fold Mirroring:** Collapsing or expanding a node in the sidepanel folds or unfolds the exact corresponding section in the document — one level at a time
* **Direct Navigation:** Click any heading to jump straight to that position in the document
* **Toolbar Controls:** One-click Expand All, Collapse All, Refresh, and Close buttons
