About this Mod
ChatTweaker
ChatTweaker enhances the multiplayer chat experience with two quality-of-life features.
Features
Chat Retraction
Made a typo or sent something by mistake? Select any of your own messages in the chat history and press Delete to retract it. The message will be replaced with a retraction notice for all players on the server, keeping the conversation clean without leaving others confused by a suddenly missing message.
Mention Notifications
Never miss an important message again. When another player mentions you with @yourname or sends a message to @all, you'll hear a distinct sound notification and receive an on-screen alert so you can respond even if you're not watching the chat.
Usage
- Retract a message — Open the chat, click on one of your messages to select it, then press
Delete - Mention a player — Type
@playernameor@allin your message
