We know that module storage is coming, very high on their priority list and it just didn't make it in time for 2.1, so it will probably be in 2.2 (i don't think they'd release it in a minor dot release).
I hope the storage space is limited, not universally accessible from all stations but only where you store it, and it costs a significant amount of creds each week for every station you have stuff stored at.
looking at Crystal ball: Ahh when other things are fixed, precisely sometime later, sooner than later, but later than soon.
That will be one gold piece for my prediction thank you ( warm, comforting smile)
