Connectors could be used to transfer crew/ resources from one ship to another or install custom escape pods
Joints could be used to cover parts of ships like connectors, The control room or the engine room, could also be used for ship details like wings or closeable storage doors
and connectors could also be used to hire low morale crew of destroyed ships or stations
makeshift parts could be used as base level parts, easy to make and could be used in a destroyed ship to push it away from enemies or to space stations where the ship could be repared
crew morale could make crew more efficient when the ship is attacked, that is if they have high enough morale, if the crew have low morale theyd be less useful when your ship is attacked and will most likely to run to the closest connector to get to another ship and run away
