Nico Comment Flow од tsukasa

Nico Comment Flow lets you search NicoNico by the title of the video you are watching, choose the best matching episode or video, and display its comments as flowing NicoNico-style overlays. It supports YouTube, ABEMA, and TVer, handles episode navigation, shows candidate video IDs plus view and comment counts, and syncs comments to playback. Playback speed, pause, seek, and fullscreen states are handled. If comment loading fails, it falls back to a simple display so the extension still works.
