2024 Status Script hasn't been updated since 2022 and is a bit broken. Sorry :( I might do another update to fix some core features but Youtube keeps changing things.
Right Side Description improves Youtube's video pages by moving the video description to the right of the video (like it used to be 2009 and earlier) and providing options to make the video smaller, have an 'always visible' retro video player bar, put the title above the video, hide end-card annotations, and additional style tweaks. (Previously known as Better Watch Page)
Requires the latest version of Firefox or Chromium (like Chrome or Vivaldi), as well as a userscripts extension (Greasemonkey or Violentmonkey recommended). Other browsers and older versions may work but are unsupported. Mobile devices are unsupported.
