Biome Journal

Biome Journal is a client-side Minecraft mod for NeoForge 1.21.5 that automatically detects each new biome entry and saves it in a personal journal. Upon entering a new biome, a HUD overlay briefly appears displaying its name and current discovery counter. Pressing the J keybind opens the journal, which lists all discovered biomes, including the exact coordinates of where you first entered each biome. Clicking on an entry displays a detailed view with the coordinates and a ready-made /tp command for returning to the previous biome. All data is stored locally in a JSON file and persists across restarts. The mod works on any server without requiring server-side installation.
