I think whatever the gender is, we really need to see the true Starfleet officer appear as the next captain.
Sure we've had the tactician (sisko), the cowboy (kirk), the diplomat (picard), the lunatic (janeway), the bumbling fool (archer) but the one thing we've never actually seen but always heard about is the Clever Starfleet officer.
Supposedly, the best and the brightest graduate from the academy, and the very top are the ones who get the good postings, so why is it that we've never seen an officer who can simply outwit his opponents or negotiate an agreement with nothing but guile and personality alone? No weapons, no equipment, no plan and still come out on top?
Sure in limited ways we've seen Picard pull this off, or Janeway stumble through blindly until it appears she did something smart, but we've never actually seen a clever Starfleet officer, let alone a captain. I don't want to say it simply to have a crossover reference, but we really need a Dr Who like "The Doctor" character to be lead captain on the next trek series and not just have someone who's able to scheme their way to a solution not be crossed off as a racial stereotype like the Ferengi or the Romulans. Intelligence is not a sign of nefarious intention.
