As per my reply further up, not every seat with a window has a viable outside view so any plan that just shows windowless seats is slightly lacking.
Yes that's good and all but it only shows the seats that are next to door pockets. Not the seats that are next to window pillars.
I'm not sure why LNER (and others, they're not the only TOC that's like this) are unable to produce seating plans that show window positions. They had it for their old rolling stock!!
