Why was the custom tree schematics option removed from MCreator?!

First off. The current custom tree option in the biome creation in MCreator 2020.1 is not good. The tree spawning is buggy, Its manditory that I put a berry and vine block, and when I do make vines. They look wonky. And there used to be an option were I can import custom tree schematics, but it was removed for some reason. Please add the custom tree schematic feature back so my trees work. Thank you.
