I've been looking for this for a little while and I can't seem to find it until i stumbled on DK22Pac's GTA IV HUD mod which consists of this feature. Well, i can't actually get it because he actually didn't post a download link of some sort (i still love your work _DK). If someone actually found or made this mod, I would want to use it for personally reasons and not upload it without your permission.
If people doesn't know what i'm talking about, this is what it looks like:
If someone actually made this, i would be very thankful.
