I want narrow margins too. Newspapers were always crappy to read because of the word spacing, word breaking, and handful of words per line. I cannot believe they were easier and more conducive to reading due to the narrow column. They were headache inducing. And now newspapers are all but extinct. Even an iPhone 6 Plus or any other large screen smartphone is still narrow enough to do away with the margins and still be able to see the entire line of text. Besides, I could care less about research. What works for an individual might be totally unique, so why not allow us to set the damn margins as we want them set. It isn't like it cannot be programmed or that the universe would implode if they allowed customized margins!
