Low priority change request, as discussed in IRC.
Would like to somehow indicate on the HUD that a player is not in the same zone as you. Currently, if out of zone it displays 0.0 in white color. This is the same as somebody in the same zone who is actually 0.0 distance from you. Discussion led toward simply coloring any result of 0.0 as an alternate color as it is an unusual state to be in regardless. This option would likely not impact performance or FPS.
