I'm sure you already have it listed as a possible goal for List features, but one of my top Wish List items is ways to search, filter and browse multiple people's lists that are offered for trade or wanted for trades.
Starting at one particular plant variety, or one person's list, isn't my preferred approach. I would rather search everyone's lists at the same time, but specify general things like genus (or genus and species), or common names like 'tomato" along with characteristics like "determinate" or "cherry" .
Or "lettuce", "romaine type" and "recommended for summer" (although that last category is not a data detail in the Lettuce database, and hard to define anyway).
