Or some other kind of zooming function. It would really help in places like the Maedracan Desert where MevNav lurk behind every corner (yes they've served my ass back to me on a silver plate more than a few times, because I get lazy and don't go to the Watchtower for the destroyer) and really, just to get an idea of what's actually out there before getting there.
This would be pretty cool. Would be relatively easy to implement, too. The only issue I could foresee is that distant models might be less detailed, depending on how Syrsa's optimized the game.
