The exchange could use an overhaul, but with the release of the Duty Officer system, the most important change needed is to be able to search for DOFF type. Right now all you can do is search the name of a listing. This happens to work well for most items, even bridge officers, because their description is in their name. Duty officers have unique names that don't convey their position or traits. This means you have to scroll through all DOFFs posted, and of course you'll only see the 400 cheapest listings. Please add in a way to search for the type of DOFF and/or their traits. This will make finding what you need so much better!
