John Pace, Head of UI at Frontier today confirmed that module storage would go live in the the upcoming Beta 5 release (likely but not confirmed to be released at some point this week).
Module storage is coming in Beta-5.
It will need a good ‘ol bashing from you Beta folks to iron out any remaining stinkers. So STORE EVERYTHING! (then unstore everything AND STORE IT AGAIN!)
Module transfer, and Module storage are essentially the same feature. You transfer modules between ship->storage, then storage->ship.
However there’s a ‘Mass Storage’ option you can use to place multiple modules into storage in one fell swoop. Handy when you’re parking that ship for a while, but still want to use it’s modules in your other ship.
