As I recall, in the pre-1.10 days, if you were part of a mission, your front end showed all the mission members' icons in yellow, as well as their dots on the dar. Of course, if you weren't in the mission, they all looked green like any other group of friendlies going somewhere. Nowadays, only the icons are going yellow, dot dar still shows them green. Often wondered if that was a bug or if HT changed it on purpose.
