It would be very helpful if the view could be incorporated into the final version of Scrivener for iPad as with the Mac version, in that you are able to change from “standard” view to “nighttime” view. Mine (on the Mac) is normal for the screen as you see it originally, white background and black font. The expanded view is black background with fluorescent green font. There are time that the change is easier on my eyes, especially at night when I’m still reading and writing in bed, or elsewhere in dim light or a darkened room. :mrgreen:
I don’t know if someone else has mentioned it, but being able to “highlight” text would be a plus, with different colors of course. 
They may not be a whole interface toggle like this, but we definitely do plan to have a “full screen” mode that lets you focus on the text, much like the Composition mode, and allow you to customise the colours that are used for it.
