Night mode

During the day I like the scriptures with a white background and a dark font. At night if I want to read the scriptures in bed, the dark on white is pretty bright. Similar to the iPhone's new night shift mode, it would be nice to simply set hours of the day for the dark color scheme. There is always the setting but it's inconvenient to have to do that every night to avoid potentially waking up my wife with the brightness. Anyone else think that's a reasonable idea?

On Windows there's an "auto theme" feature that uses your ambient light sensor to turn on the night theme automatically. It'd probably be a good idea to suggest the same feature be available on iOS. I'd suggest it via their feedback email (located in the app) so that they can get the feature suggestion.
