My wife (Vio) and I were discussing what some further uses of beans could be and we think we came up with a couple of great ideas.
First off, we'd need a new piece of equipment that could convert beans to more specific types of beans, not just tree seeds.
Barista: This could benefit from being able to create a Coffee Bean. There are loads of different coffee based drinks that could be created from a skill like this, possibly having a continual energy gain effect over a period of time.
Confection: This could benefit from being able to create a Cocoa Bean. All kinds of candy and cake-like goodness could come from this.
