Would be a super easy 5 stars with a few configuration updates:
1. Allow specifying different types of seeds. I'd like to plant snapdragons in the S-tier patches (e.g. Catherby) and then irits in the shitty ones (e.g. Canifis)
2. Allow disabling certain patches. I like to keep white Lillies in some of my patches to protect allotments, but this will try to harvest them.
Update these two things and this is an easy 5 star and I'll probably run it 20 hours a day.
