I simply cannot comprehend why there has been no response from the Evernote development team to this issue. I adore Evernote. It has been a boon to my songwriting, etc. BUt so much of that writing takes place at night, in darkened spaces, and I am left with a purplish rectangle in my field of view as I try to move about the house. I am not especially knowledgeable on these matters, but I fail to see how it could be that difficulat a proposition to give the ooption of a dark screen on my Android phone. Seriously, what is the Big Impediment here?
