I recently swapped out my science officers. My science officer that I've had since the beginning of the game is now, by coincidence, in my ensign slot, and my new science officer is in the lieutenant spot.
BUT he's not supposed to be my chief science officer! I don't want to see his ugly borg mug every time I get a science report! Even if my old one only comes with me on ground missions, she's STILL my first officer!
My suggestion: Since we've got those awesome department head selectors in the Doff system, how hard would it be to use those for the different bridge officer reports, instead of simply whoever occupied the highest-ranked console on my bridge?
