If you mean you have a bridge officer with the creativity trait, I would expect it would apply to their ground powers. Kits and BO powers are the same thing, just differently implemented. For a captain, you get your powers through your kit, but BOs get the same powers through their 4 ground abilities.
There are benefits to doing it this way. As a captain, you could swap kits and try out different powers easier than you can change a BOs abilities. For team play, you could carry multiple kits and use the one that best suits the team you are currently in.
In looking further into these traits while re-working my Bridge Officers, I noticed another thing: Covert trait on engineering officers?
As far as I know Engineers don't have access to any stealth items/modules/kits, etc. So would this be a wasted trait for an Eng BO?
Another question would be... if I'm a human with +15% repair rate from leadership, if I add another Human to my crew, will those bonuses stack?
Also do you only get the space bonuses from seated crew members? i.e. BOs manning a console, or would those buffs apply from members of your crew that are not assigned to a bridge slot, just on the ship?
