That would be nice to be able to preset the bridge officers uniforms while creating your own, that way, when you get a new officer , you just click once and get the right uniform, without having to do it form scratch.
Ability to change material on the uniforms? I like soft fuzzy look of the TNG movie uniforms, but I'd like to be able to apply that texture to some of the other choices. Too many of the other styles are all rubbery looking.
-More hair styles (longer hair styles for male and female)
-Lab coats (possibly unlocked if you max out the "Doctor" skill or something)
-Dress uniforms (such as the ones on "Insurrection")
-More jacket looking tops (such as Admiral Quinn's, or Picard's "Boss Tweed" jacket)
-Pips that update to your current rank (unless you specifically go in and change it)
-Shoulder Patches (such as on "Enterprise", which can reflect your fleet, or ship)
