Biome Notifier informs you of new biomes, without having to keep the F3 debug screen up. For the first time you encounter a biome, there will be a larger notification with its own sound effect. Thereafter, you will see a smaller notification in the corner of your choosing.

Entering a biome which you have not yet explored in that world will cause a big discovery message to appear at the top of the screen accompanied by a specific sound. Entering the same biome again at a later time will cause you to receive a smaller, quieter discovery message which can appear anywhere that you choose to configure it in the settings menu (top left, center, or top right). There is an internal journal screen to record all discovered biomes with search capability.
