It would be really nice to have either a "percentage earned" or a number system in regards to the villager's skill. Sometimes when they are adept it is hard to tell how much farther they have to go until they are masters.

Also might be nice for a trading post too where you could trade food for tech points if you have a ton, or tech points for food if you are starving.

I don't think the kids should be able to pick up the mushrooms and collectables on their own (that's half the fun of it) but since the kids can start healing at a young age, maybe they should gain a little farming experience after they pick up so many mushrooms and maybe research experience for the collectables.
