Omarock (ID: 0000008281cb65de) Voted 5 ★ - Updated 01/03/2024 Amazing extension! I would suggest adding support for full screen and vertical resolutions (kinda like "Enable Portrait Mode " option on FrankerZ extension for twitch where it places chat under or over the video), would take it to the next level!
