Plugin needs to be modified to queue island generation. It crashes if the amount of islands you want to generate is too large; which makes it useless if you want to make an entire world of islands.

For reference, I have an 9900k (5.1GHz core, 4.8GHz cache), 32GB (16 of which was dedicated to the server) 3800MHz cl14 RAM, 1TB NVME SSD. All of which should have been powerful enough to handle generating a 10k x 10k world of floating islands.

My only other option would be to generate islands in sections, manually...

this can be a good feature if the plugin gets more update can be very good because there is not much world gen which gen islands
