Spammerino - Twitch Chat Enhancement is a Chrome add-on developed by yzn20080. This free program provides several handy tweaks to improve your Twitch chat efficiency.

One of the main features of Spammerino is the Repeat Button. After each message in Twitch chat, a button is added that allows you to send the exact same message again with just one click. This can be especially useful for sending repetitive messages or commands.

Another useful feature is the Message Hover-pin. When you hover over the chat history area, Spammerino auto locks the chat history for you. This prevents the chat from scrolling under your cursor, making it easier to read and interact with messages.

Spammerino also offers Chat History Emote Clicking. Instead of typing or searching for emotes in the emote menu, you can now simply click on an emote in the chat history to send it. This saves time and makes it more convenient to use emotes in your messages.

In addition, Spammerino helps with resending rejected messages. If your message fails to send due to slow mode, r9k mode, or being identical to the previous one within 30 seconds, Spammerino will automatically wait, modify the message if necessary, and resend it for you.

All of these features can be customized or disabled in the options menu, allowing you to tailor Spammerino to your specific needs.
