Well, something like this has been suggested many times before, but I think it would really improve gameplay in realistic mode.
The basic idea is: What can or cannot be see in realistic mode should be somehow visually discernable.
This is a little rendition of mine, what can't be seen has the colour reduced (to 50%).

A visual indicator like this would make it immiediatly obvious that you have joined a realistic mode game.
But The main reason for such a thing, is for players to know exactly where they can or cannot see.
