This plugin is interesting. Could you add a few more things?

Instead of:

blocked_worlds:

it would be:

active_worlds:

So that it activates in the world you place, because I'm sure many of us have too many worlds, just like the EliteMobs plugin, which has too many worlds.

The default icons that come by default in each biome in the config.yml is very useful, also the colors. Very nice plugin

The CustomBiomeAnnounce plugin is an excellent choice for servers aiming to enhance the exploration experience! Players receive stunning notifications when entering new biomes, with customizable titles, sounds, and chat messages. It’s lightweight and optimized, making it a smooth addition to any server. The easy configuration and world blacklisting features make it incredibly versatile. With planned updates like particle effects and action bar messages, this plugin is perfect for survival, adventure, or RPG servers looking to add a dynamic and immersive touch to gameplay. Highly recommended!
