+1 for second-levels of all the skills like fruit-changing and spice-milling. What we could do is also stagger the recipes which are available, and each level of the fruit-changing skill would let you make more, and also quicker and with more experience.
Agreed. It would give some people an advantage while working on projects (obviously this is a reference to that with the cloudberries and bananas haha). Or maybe the highest level you can change two fruits, spices etc at once?
