I think it would be very nice if we added an account console (the thing that lets you access the bank records) back to the captain's office. There is one in the XO's office, and the captain used to have one, but it disappeared several remaps ago. A simple quality of life thing for captains rather than having to go to the XO's office to check the account records when it is needed.
In a similar vein, adding at least one ATM to the inside of the bridge (if not in both the XO and captain's offices) would be very helpful in transferring money between accounts. As it stands now, you've gotta go out of the bridge and find an ATM to make any transfers between accounts. Time consuming!
