Introduction

At the bottom of this page, you can find a screenshot showing how this script works.
Please check it before installing.

Overview

This userscript makes Twitch’s Chapter list easier to use by expanding it vertically,
so chapters are easier to find and scroll through.
Click to expand, and right-click to adjust the height (screen occupancy).

Features

  • Expands the chapter list area for easier scrolling
  • Adjust and save the expanded height in real time via right-click settings
  • Retries briefly to remain stable even if Twitch’s UI loads slowly

How to Use

  1. Right-click the “Chapter” button
    → A settings popup will appear, allowing you to adjust the height with a slider
  2. Save: Saves the setting (applied next time as well)
    Cancel: Reverts to the previous value
    Reset: Restores the default value
  3. On a Twitch archive or live stream page, click the “Chapter” button
    → The chapter list will expand vertically according to your settings
    Close the settings popup: click outside it or press Esc

Settings (VIEWPORT_FRACTION)

  • Determines how much of the screen height the chapter list occupies (excluding margins)
  • Range: 0.10 – 0.70
  • Default: 0.40

Requirements

  • Tampermonkey (Chrome recommended)
  • Target site: twitch.tv

Notes

  • This script may stop working if Twitch changes its UI, button detection, or class names
  • It may conflict with other extensions or custom CSS themes
