Hello!

New trees are always nice, but they require devs to add a new biome with them inside. A possible solution would be to have some kind of mutation. Here me out:

• Breaking leaves from a regular birch tree could have a tiny chance to drop a yellow/orange-leaved birch sapling.

• Breaking spruce leaves could sometimes drop a sapling for a more reddish variation of this specie.

Then there is potentially trading with villagers. What do you think?
