Do you mean a clear view, no icons, when composing? Have you tried cycling through the 'display' options? Pinpoint mode? As in, pinpoint focus? I only ever use the select focus point, next to the 'pinpoint' - when the pin point wanders click display to get it back to center. I'm not sure I get exactly what you mean :/ this will be something I'll learn here too I think

If you mean the little window that pops up as you are composing in that focus mode, I don't know how to keep it on screen after you focus ... but I don't know why anyone would use this focus mode to begin with tbh. The SP focus selection is way better, and more adjustable.
