I would like a feature that reports safe/lost to the team overlay.
That way, you can see if a location is lost or safe by looking at the overlay, and the team messages will get less cluttered.
I don't see this as practically doable for several reasons, but mostly because it's subjective and subject to change at any given time. In other words: There isn't a clear definition of when something is safe and when it's not. Triggering on user messages isn't usable either, then it will misinform more than it will help.
Unless presented with a complete solution thats only to implement, this won't happen unfortunately.
