Added new AllowedBeamBlocks config option. Materials listed here will hide the beam, but not disable a beacon when placed above. Tinted glass is added here by default on new installations. If you already have the plugin installed, make sure to delete your config.yml and restart your server, or manually add:
AllowedBeamBlocks:
- TINTED_GLASS
The plugin doesn't require Paper anymore, and should work properly on Spigot
