I have had quite a number of users contact me privately with unopenable files, from this version.
The best I can do is extract a hexadecimal file with smatterings of real text scattered within the code.
Of course until that happens to you, that is not real.
When it does, you too will be a Niagara of tears, and "Nobody told me!".
If you remove most of the features and hide the rest, yes there will be the illusion of simplicity but I am a designer and the so-called Contextual User Interface is hardly contextual and has been so badly implemented that it is the cause of nearly all the posts here.
People simply can not see or find things that are out of sight or deeply buried within an oddball UI structure that repeats pointlessly on each and every document, consuming screen real estate for no purpose.
