I was afraid that might be the answer...thanks for clarifying it.
Imagine this dialogue at the pre launch NC software development table:
"Hey, let's put some banners on the books that don't always function as they should, that most readers won't want and will find annoying, and then not give them an option to turn the function off!
Why waste time on a useful (and simple) notepad feature that almost everyone would want and use when we could do this instead!!"
Yes, I know the above is really cynical.
