Copper golem smarter sorting

First off I think that the copper golem is really cool, but one thing that really hinders it is that when it can’t find where an item should go it will only put it in a completely empty chest. I think it would be better if it would put the items in empty open spots or make a way to take items from it. Also it I think that only sorting into 10 chests is a very small amount of chests and it would be better if it was confined to a certain radius from the copper chest.
