Insted of inventing different types of ashes I don't get why not change it so higher level wood types gives more ashes. And ashes could be used in farming to give extra crops. and to make woodcutting better I think it would be cool if for holidays like Hallowen they added spooky wood and for Christmas they added Jolly wood from Christmas trees and cherry blossom trees for chineze new year and other trees for other holidays so woodcutting would be a job more people would do on the holidays.
