With "have it made" I meant, they have it implemented in their mod I've seen it. Dunno who originally coded. 88flaks? oh well, now it's time for Discovery :]
From what I remember, 88Flak and Disco have a very love hate relationship with the 88flak guy(s) accusing Disco of stealing their coding and such.
That said, Making a visible waypoint for group members would be great. What would also be great in my opinion is the ability to see every grope member in system map. I believe it's been done on Itano Circus though that was years ago when I first learned how utterly crap I am at PVP as well as before I properly got into Disco. However, I think Alley and I discussed this at some point in the past and she told me it was near impossible to code. Not sure though. Maybe it could be possible to code it so that only the group leader shows up on the map instead of a random group member?
As for the Autopilot waypoint system... My opinion of this idea is that it would severely diminish the reason this mod and community exists, which is Role Play. Mind you, I'm a hopeless romantic when it comes to this subject, but this community is based around RP, if a trader sets a course that completely avoids any major areas that pirates or lawfuls looking for smugglers frequently lie in wait, then it makes it that much more difficult for those looking for random RP to find it.
