Custom Window Title Mod (1.21.8, 1.20.1) – Personalize Minecraft’s Title Bar with Live Info

Custom Window Title Mod (1.21.8, 1.20.1) enhances your Minecraft experience by letting you fully customize the game window’s title and icon. Instead of the default “Minecraft” label, you can display real-time data such as FPS, coordinates, version numbers, or even your username directly in the title bar. Perfect for modpack creators, streamers, or players who enjoy fine-tuning their interface.

Features:

• Replace the default “Minecraft” window title with a fully customizable string.
• Use live variables like:
  • {mcversion} – Minecraft version
  • {username} – Your Minecraft username
  • {modversion:mod_id} – The version of a specific mod
• Swap the default Minecraft icon with your own .png file, allowing full transparency support.
• Lightweight and non-intrusive; works client-side only and does not affect gameplay.

Configurations:

• File Location: .minecraft/config/customwindowtitle-client.toml
• Editable Entries:
  • title = "Minecraft {mcversion}" (can be anything you want)
  • icon = "customwindowtitle/icon.png" (for Minecraft 1.21+)
  • For older versions: icon16 and icon32 are used

This configuration system makes it easy to integrate branding or debugging tools into your Minecraft setup.
