Fomo

A BepInEx mod for On Together that enhances the in-game chat with configurable message limits and in-game utility commands.

Features

• In-game commands :: Toggle and configure all features without leaving the game
• Configurable chat history length :: Increase how many messages are visible in the global and local chat windows

Looking for WebSocket support? Install the FomoWebSocket add-on. Looking for chat file logging? Install the FomoChatLog add-on.
