Not if there's nothing in the room. All you'd need to do is draw a couple of rectangles under the map, so I don't know why you're so critical of this. Then again, you really have no clue when it comes to user experience.
>user experienceAnd we’re talking about “user experience” as in, “Oh my design needs to be fancy and appeal to the user, and it needs to be really EZ so the user doesn’t have to conjure up much intelligence”?
If you have nothing in the room, you’re probably going to put stuff in it, or just leave it blank. And when you put stuff in it, then it gets EZier to see the room viewport boundaries, even though it’s already EZ. The only reason it would be not-EZ to see the viewport boundaries is something about brightness or contrast on your monitor.
