Hello there,
one thing I am currently very much wishing for: containers to hold rocks, ores and soils.
It would be so nice (and natural) if I could use my wheelbarrow (or a cart) to transport them from the extraction site to where they are used. I read the Trader cart can, but I haven't build one yet myself. However, it would only make sense for the "lower level" movable containers to be used for such a purpose to, after all, if my backpack can hold all this stuff, why shouldn't a wheelbarrow?
