Non-full placable blocks (torches, snow, seeds) cannot be placed by the undercutter cart, but can still be placed in the filter

just as well, any non-solid blocks placed in the filter do not get replaced

If this were a mechanic, the undercutter cart could be used for cart-powered farms, as opposed to the alternative of hopper-piston based farms

Either way, can the undercutter cart have the feature to "clear" the sides, instead of being replaced, and place without having to have something to replace

Discuss!
