So if I have a sorting system using a dozen storage modules each of those storage modules will need it's own separate cargo area defined?
With a shipyard you can kind of do this already. Repairing a ship will put all it's cargo into the shipyards storage.
After all it is going to be a pain to sort them all in huge areas again.
also including the ability for sending items between the storage of different entities
For how I understood what was said.
If you want to keep an old split of blocks separate all the time, you would need a cargo area for each group.
I imagine more people will end up using a few large generalized cargo areas, naming them and using the filter more often.
For a sorting system I think you would start with at least one large enough to hold the player inventory amount. (until cross entity transfer)
The speed of sorting and moving cargo will be limited by the cargo space of each step in the chain.
I really do think this is a step in the right direction. Mine a planet, and be proud when you make the cargo zone to hold it.
