Besides Officers (that feature is a given in the near future), I would hope for the first draft of the economy system.
What that might be like, exactly, I have no idea. Though I'd certainly like it to be kept somewhat abstract similarly to supplies/CR; generic resource goes in, fleets/weapons/ships/supplies come out.
Perhaps a little diplomacy could be introduced with that; bringing resources to a hostile station could give an option to 'abandon' them nearby for a small relations boost.
I'm getting ahead of myself, but that's what I would like to see.
