I have an idea for a Farming seed pouch. It slots into your tool slot, available in Loggia/blue/Manos. The higher enhancement levels provide more slots for more types of seeds. It can provide a place for your seeds to stack as well as provide farming mastery/exp gain since we currently don't have any tools for farming. Feel free to add to the idea, thats all I can think of right now.

Maybe a seed pouch. To hold your seeds. Stackable seeds.
