Capital ships and player stations will ultimately use the same system for ship storage.

[00.48] (EMG)-Oobfiche: oh and is the station UI inventory being removed in favor of the storage/hangar/factory areas?
[00.48] LauriFB: that's the plan
[00.48] (EMG)-Oobfiche: ok cool
[00.49] LauriFB: physical storage that is, ie. physical crates or various different areas
[00.50] LauriFB: all connected crates form single inventory
[00.51] LauriFB: starter stations will keep their magic station inventory, but it's limited to certain amount
[00.51] LauriFB: also ship despawning stays at starter stations
[00.52] LauriFB: but player stations and capital ships use hangars, which are physical storages for ships
