Also known as "BTTV" or "Better Twitch TV" by the community, BetterTTV aims to add new features to Twitch's website.
Here's just some of the features we add to chat:
• Calculated username colors – AKA spring green (etc) begone
• Extra emoticons – BetterTTV global and per-channel emotes
• Username/Word/Phrase highlighting
• Word/Phrase blacklist
• Split chat lines for easy reading
• See deleted links and messages
• Unban all banned chatters with /massunban (channel owner only)
• Anon Chat – join a channel without showing in the user list
• Link preview when hovering over links
• Image preview when hovering over image links
How to use:
• Just install and visit Twitch to begin using the add-on.
• Options can be configured in the chat settings or by clicking the BetterTTV settings from the user dropdown menu on Twitch.
