Any suggestion of adding more UI makes me cringe a little. The minimalist style that has been in goio since its release has forever been something I like and want real no additions to when it comes to in-match. It keeps everything less cluttered and more focused on the game rather than staring at bars all the time.
As for determining what is broken, I feel that is the captain's job to know what is broken, and what he wants fixed as priority. Engies do run about and keep a ship running, but it is a captain's responsibility to let them know of imminent issues, and adding more UI would take away from that level of communication, and potentially lead to confusion.
Nothing personal, but I am firmly against more UI for in-match. The additions to spectate were nice, but only for spectate.
