Non-rented player using storage to the colony page would be nice to keep track of any stuff hiding in a abandoned station somewhere.
Reminds me of something tangentally related. Better lists. The current lists are woefully inadequate. Item list in colony is useless because it lists all of the commodites the colony produces but almost none of the weapons and special items stored, since the commodities eat nearly all of the alloted spaces before hitting "...and more". Similarly, after I store a bunch of ships there, only a small fraction of the ships are displayed, and it gets annoying when ship types are effectively displayed twice because some are clunkers and the rest are pristine.
Perhaps for ship types, have something like clunkers/pristine. For example, if I have Falcons in storage, instead of and 5 Falcon (D)s taking two slots, something like 3/5 Falcons or 5/3 Falcons. That would help squeeze more ships in the list. Of course, this does not help items since all of them do not have degraded versions, except nanoforges.
