Would be cool with a function like : stop producing when buff go off. It could be a button on each production building.
Or like : Only produce when buffed.
And another : Rebuild all well's / Wheat field's. This stuff can take ages^^.
This could be on depleted field's and well's.
Also it would be cool if starmenu building's (noblets,recycler,watermill etc.) could keep their upgraded level if it's thorn down, open the possibility to sell upgraded deeds and have free moving on these costly buildings,hehe.
