For some reason the FO4 HUD doesn't indicate non-enemy entities, so its quite possible to miss companions and settlers, even when surrounded by them. Cant tell you much time I've wasted trying to find, say, Dogmeat - who may only be a few metres away - but is invisible as far as the Pip-Boy and HUD are concerned. Don't get me started on the amount of times I've told a companion to "stay" outside of a building, only to lose them and not be able to go pick them up later, because neither the map, Pip-Boy or HUD gives any indication of where they are... So, I would love, love, love to see non-enemy blips, so you can tell where potential allies/companions/traders are - pretty much anyone who isn't trying to kill you! Thanks for reading!
