It's something that Simon's interested in doing, although he says it relates back to how they're going to manage what information is being shown, when it's being shown, and how. If they get to a point where the on-screen icons have been cut down to a sensible level, then they could consider whether it's worth having PoIs visible in other modes as well, and thus it'd be something that's worth having them look into. He says it's definitely the sort of thing you'd want to try out as you're developing it so that it can be iterated upon.
