Am I the only one who thinks that an ordinary cobblestone generator on a skyblock is boring?
That's why this plugin appeared! It allows you to customize the cobblestone generator however you want.
It has a flexible configuration for configuring the plugin which includes:

1. Support for any vanilla block!
   
2. Setting the chance of a certain block appearing
   
3. Creating the 2nd (lower) layer, where any other blocks will be located
   
4. Setting the default block for different layers
   
5. Setting the height at which the bottom layer starts
6. The ability to create templates for generators
   
7. The ability to change the template at any time using the command

Get rid of the old and boring generator that is already outdated and try this plugin that does not load your server.
