very satifying and well made plugin! I do feel that it has loads of potential for example making wells water will fill tight spaces all the way to the top. and maybe the water source could transfer at the end of the vanilla water flow blocks

This is a super cool plug-in. Right now it is experimental so it can cause chunk generation to halt at times. I would definitely not recommend for a production environment at this time but the idea is awesome and deserves a look. I absolutely love watching oceans fill an entire underground cavern or lakes flooding a valley and reforming at a lower position. Thanks for sharing your work with us!
