I want to be greedy and say "Please give us the ability to freeze plants in ANY state, not just fully bloomed!".
For example, the second to last stage of the cherry tree with the tiny red leaves is super pretty, I'd love to keep that! Or the tiny violet flowers before flax seeds fully grow. In the other thread someone also proposed to make it possible to harvest dried plants from the pots to put them into vases to allow for more eerie housing themes. I fully support that idea °-°
