Hi @waterleat - welcome to the community!
The “bed generator” was a feature in farmOS v1, but was not ported to v2. Instead, you might be interested in @Symbioquine’s Land Drawing Tool. See this forum post: Bed Generator in v2?
Great! If you’re interested in joining one of our monthly calls (or weekly dev calls) I’d be happy to help brainstorm with you!
The “Crop / variety” vocabulary is the main one… this is referenced on Plant assets to indicate what type of plant it is, for easier filtering/searching.
The “Crop family” vocabulary is intended to be used for botanical families like “Brassica”, which you can then reference from “Broccoli”, “Cabbage”, “Kale” etc terms in the “Crop / variety” vocabulary. This is optional, though. It was originally added as a step towards facilitating rotations (to ensure that you use crops from different families), but no features have been built yet to leverage it.
FYI farmOS v4 is does not have a “stable” release yet, and is still very much in development. I would not recommend using it until 4.0.0 is released. Things may break before then.
I would recommend using the current “stable” release which is 3.4.5.
