I had heard of seatexpert but never been there before. Interesting site.
I'm not going to vote for it.....because that would be a vote for you to do something which, more often than not, is not going to be helpful to me. Wouldn't it be just as useful to add such comments to the written descriptions? With something as minute as windows, aren't you going to chance being off a bit....only to frustrate someone down the road? Are the windows going to be lined up exactly in relationship to the actual location of the seats?
It seems a bit more intense than what's needed.....but if you've got the time, sure -- go ahead! :-:
