Well, now...
That's an interesting, and very original request.
I don't now if I LIKE it... But I grant that it's got merit. I like seeing where friendlies are (mind you I'm not a "spy"), so I can judge where a good fight is, see what's going on, see if anybody is defending field "X" and so forth.
If you still showed up on dar bar as friendly green, that would be a great suggestion.
