I've Spoken
The I've Spoken mod introduces a unique character dialogue display system to Minecraft. When a player says something in chat, a stylized RPG-style window appears above their name showing the message text, which smoothly disappears after a few seconds.

If the message text is too long, it's automatically truncated to the set limit. All mod parameters can be finely tuned to your preferences.
Configuration
Mod configuration is done by editing the config/ivespoken.toml file. For greater convenience, it's recommended to install Mod Menu - with this addon, you'll be able to change settings directly in the game interface through an intuitive menu.
