Amazing plugin, tho i would like to know if with 1.21 you mean it supports 1.21.* ?

Love the ability to define multiple schematics for a single sapling. Great addition to the plugin.

Hope add more random options, like:

cherrytree:
...
shem-rotate: true
# This will rotate the schematic by 90 or 180 degree, of course the rotate center should be the tree trunk
schematic:
- 'cherrytree_small.schem': 50
- 'cherrytree_big.schem': 50
...

This plugin is good, keep going!
