I haven't looked at this for a while but last time I checked, if you set a player red they show up the exact same colour as NPCs.  Would it be possible to have an option to change the red NPC colour to something else (pink)?

That way you won't confuse players with red standing with NPCs etc

Would also be nice if you could make squad members purple on the radar so that they are a bit easier to see against the background colour.
