Description:

This script aims to improve the theater mode on YouTube as the default theater UX is atrocious. The goal is to copy the nicer design ideas from Twitch.tv while still maintaining YouTube's unique UI features.

This script relies minimally on setTimeouts and instead relies mostly on event listeners and observers, making it reasonably performant. Design-wise I would like to think this is a reasonable compromise between the Twitch design and the current YouTube design, which should, and I hope, would maintain better compatibility with YouTube even without constant updating.

Features:

  • Extends the video player to the bottom of the screen in theater mode (Web Fullscreen).
  • Extends the chat area all the way to the top in theater mode.
  • Makes the chat width adjustable in theater mode.
  • Fixes YouTube's fullscreen mode to work more reliably.
  • Minor UI tweaks.
  • Adds the option to allow users to move the YouTube search bar below the video player. (Feature originally suggested by tordenflesk with this feedback.)
  • Added a mirrored notification bell inside YouTube's quick action section so notifications and unread counts can still be seen even when the search bar is moved or hidden. (Feature originally suggested by Leadra with this feedback.)

Notes:

  • v1.0 would still be recommended if one wishes to use the minimal version of this script. That version is extremely light and very resistant to breaking but will lack the UI tweaks and the fancier features that got added in the later versions.
  • Tampermonkey only added dynamic menu items in version 5.4.6224. This script provides fallback logic for older versions and other script managers to maintain menu compatibility.

Compatibility Status:

Compatibility with various devices and browsers has yet to be tested explicitly.
