I just attended a series of wonderful plays at Stratford Festival. However, it was frustrating to look for have the numbers of the rows marked in straight up and down vertical. Can the numbers or letters of the alphabet be tipped at sufficient degree that one can see them. Think of "/" as an idea of the degree if angle. If these remain marked vertically in LED , they still are hard to see.
Seats can be a challenge but small arrows pointing to the initial seat in a row would help.

I was muttering to myself about just this issue so thanks for asking.
