I've seen this mod and I can't recall whether the machine for compressing/uncompressing is a 2x2 structure. I'd really like to see the potential of this mod as having a research tree that progressively allows the player to compress more and more items beginning with ore. With each 'tier' of compression research you could unlock compressed plates and have a sub tree that allows for furnaces that can complete compressed ore processing and so forth. It would be really interesting to see as an ultra end game investment in order to increase the productivity of a factory. However, it'd be a bit tedious to display the correct numbers on production if you never uncompress anything and the magnitude of the factory would feel a little off.
