Twitch Comment Overlay

Twitch Comment Overlay brings Twitch chat onto the video player, so the stream stays center stage while chat remains easy to follow.

It supports two viewing styles: Niconico-style scrolling comments and a translucent hologram chat panel.

Usage (easy 3 steps):

1. Open a Twitch stream page under `https://www.twitch.tv/`
2. When chat messages arrive, they appear over the video player
3. Open the extension popup, or pin it for easier access, to adjust the display style, language, font size, speed, opacity, rows, display area, and username display

Main features:

- Niconico-style comments that move from right to left across the video
- Hologram chat, a translucent vertical chat panel over the player
- Adjustable font size, opacity, speed, rows, and display area
- Optional usernames, badges, emotes, URLs, and comment time display
- English and Japanese UI support
- A test message button to check the overlay before using it live

Your settings are saved locally in Chrome. Twitch chat text and usernames are used in your browser only to show the overlay. They are not sent to an external server, sold, shared, or used for advertising, analytics, or tracking.

This extension works only on `https://www.twitch.tv/*`.
