I found that I was distracted today, while seeking to start a review. So I fired up Focuswriter (pictured). This removes everything from one's screen except the text. For a moment, I wanted to check some information on the Internet. There wasn't even a minimise button -- in other words, Focuswriter said no -- at least, it made it awkward. OBSERVATION: This image is not meant to be read, just to show what happens to one's screen -- this is the whole of it in Focuswriter.
