Wouldn't it be cool to be able to give the title of "First Officer" to one of your already established bridge officers, or have some place like BO Requisitions where you could pick and choose between First Officer candidates. The title could bestow like 1 special power to space or ground (or 1 to each) plus a special stat increase to a specific area in your ship's ratings. It could be something like the powers and/or stat increase varies per officer, meaning that they would have a different ability if they were sci/eng/tac and its dependant on their species/gender, etc.? I just thought it would add a bit more depth and customization to the game.
I don't know if this idea has been brought up anywhere else, but I did a search and didn't find anything.
