Wow. I am curious what performance you saw. I went Sat eve. It didn't bother me at all, but it's not something anyone with both eyes open looking at the stage could have missed. She referenced the pages throughout, flipped pages, and came up with stage business--sometimes involving other actors--to get it in and out of her hands. It did not require any special (non casual) observation on my part to see this. It was unmissable.
