I gently ask if you can implement the shells on the sea shore (also to make seashore more realistic) that those who have the desire to also collect them and then make their own personalized things like decorations for buildings, necklaces etc ... not only for himself but also wanting to sell or barter with other players. This also to have a little more distractions while aspects harvest, you're done the work and have their own manpower of various things in this case with the shells.
I'm sorry for my english.
