Some possible improvements

* Players easily forget to confirm ship change after moving items to another ship. What about also making a warning if a ship has empty item slots and there are available items to be put into them? (probably with a "don't ask again for this setup" option)
* It would be nice with arrows around the ship also indicating friend locations (and probably the distance through arrow size/acuteness) (use a different arrow texture, e.g. a dotted one, to indicate it's friend not enemy). It's also nice to have arrows of different colors to indicate locations of different ships.
