Morgeo: I would like to see a RED dot in my friends list if they are playing.
This was first suggested by Nivlac as early as in December 2008; unfortunately, we still only have those misleading green/grey dots today. See an earlier discussion of the proposed mutiple colours of dots.
At the very least, WGT might arrange that the green dot, by default, becomes the grey dot whenever someone enters a round or skill challenge, and automatically reverts to the green dot whenever a round of golf or skill challenge is over. Yes, you can regulate the green/grey dot manually through 2 clicks of your mouse, but this is so bothersome that most players don't really care to do so. They are right, the software should do that for them automatically (while, of course, still leaving us the option for manual adjustment of the color of the dot, as it is today).
