I know that some of the bridge officers we get awarded to us can have improved stats or rare abilities that can't be found at the regular trainer. However, not all of us know every trait and ability in the game. So, it would be nice if there was some mouse-over information on the rarity of the skill or the bonuses to the given stats. For example:
Say we have a Klingon officer who has +15% melee strength. It would be nice if, when we mouse over that information, something came up saying *+5% bonus or something.
Or on the space/ground skills, add in a colored "Skill not available at trainer." note. That way people would know whether they should consider the officer for either their stats or for training someone in their advanced skills.
