In my opinion mine Elevator should enable us to put liftables inside. like they are pretty good to drop food,and some metal for pillars down to the mine, but except for that they are pretty useless...
change their inventory to at least one liftable space(chests can work as inventory grid as well) so we can at least move ores up and down with wheelbarrows.
Or because you need to prepare space for them first, let us select with flower menu how deep we want to go and port us there. that would be easier than clicking on each minehole up to level 9 >.<
