I would like an add-on that lets me use the vines and grass from the new gamemode, solar apocalypse if you have played it. I like having the spreading vegetation and would like to be able to use it on my regular builds rather than just in that gamemode.
Perhaps even more plants that spread, such as trees and such, but definitely with some way to control their spread with commands or something. Like a /clearAllVines and stuff like that.
