We all know about Captain, Head of Engineering, First Officer, and so on, but what new Star Fleet position would you create? I could go for something like an onboard diplomat. Would be there to settle any political matters and first contact situations rather than anything to do with running the ship. I think that would lead to some interesting conflicts and debates with the Captain, especially since such a character wouldn’t be so set in the command hierarchy. I guess a little like a Soviet political commissar, but a benevolent one.
