CyTube Plus od Hostu404

A tidier look, coloured names in chat, highlighted mentions and PMs, a lights-down button, Niconico-style comments that fly across the video, and a switch to turn off sync and watch on your own. Unofficial, not made by CyTube.

Features

• Polished look: the chat, playlist, poll and video become rounded, tidier cards, and busy chats and long playlists take less work for your browser to draw. A channel's own style still comes first.
• Coloured names: everyone in chat gets their own name colour. Staff keep their rank colours.
• Highlights: messages that mention you, and private messages, stand out.
• Lights down: the bulb button under the video dims the rest of the page. Click outside the video to lift it for a moment. How dark it goes, and for how long a click lifts it, can be set in the menu, and the chat can have a lighter dim of its own.
• Niconico comments: the square button under the video makes new chat messages scroll across it, emotes included, in fullscreen too. Coloured text like greentext keeps its colour, and the speed can be set in the menu.
• Turn off sync: pause and skip the video on your own, or click any title in the playlist or search results to watch it just for you. A bar under the video shows what you're watching and takes you back in sync with the room in one click. On channels that hide their playlist, the bar has a searchable list of it instead.
• Click names and emotes: click a name to reply to someone, or an emote to add it to your message. Where a channel has its own click features, those come first.
• Shrink big emotes: oversized emotes in chat are made smaller so the chat reads more easily. Small ones are left alone.
• Blacklist: turn the add-on off on any channel you choose, or with one switch for the channel you're on.

Everything can be switched on or off from the toolbar button. It only runs on cytu.be channel pages and collects no data.
