Better Chat is a complete replacement of the in-game chat. Better Chat is better in a lot of ways, with features such as:

• Built-in emotes
• Easier to read names and club tags
• Right-clicking player names for options (spectate, Trackmania.io profile, block, etc.)
• Highlighting on @ mentions
• Custom chat commands
• Autocompletion for mentions, emotes, and commands
• Blocking & filtering
• Streamer mode to censor some bad stuff

This plugin is open source! Feel free to report issues or contribute on Github: https://github.com/codecat/tm-better-chat

Known issues

Better Chat might not work properly on some Pyplanet servers, due to Pyplanet doing some weird custom chat stuff. There's a Pyplanet Github issue for it here.
