Currently it is possible to see the number of pages read per day if you sort stats to a specific month. It is also possible to see number of pages read per month if you sort stats by year. I think it would be really cool to have a graphic on the year page that tracks a rolling 5 or 7 or 10 day average for you number of pages read. That way you can see the weeks you were reading a lot vs a little, and it is a fun way to try and keep your average up. If a rolling average is too hard, even just a pages read per week, Mon-Sun, chart for the whole year would be really cool.
