I just wanted to drop by and maybe leave an useful information and idea for future development.

I'm a big fan of BoP as it has always been the best world generator out there but today I stumbled upon this (curse link) and it is a very well built GUI for custom world generation. Since more and more people are getting into modded minecraft such user friendly (aka noob friendly 😄) application is a game changer imho in the modded MC ecosystem.

Closing this because we either can't/won't fix it or it's not an issue in 1.13
