This idea has been merged into another idea. To comment or vote on this idea, please visit VER-I-373 I would really like to see percentages of the material that you know. Also, maybe a number count of how many you know would be interesting to see..
This one is actually in development already! We had the same desire so we're building in some analytics. But we decided to go a little further than just analytics. :)
We're building something called a "memorization assistant" that will include analytics but go beyond just displaying them and actually use that data to help you memorize more efficiently. Among other things, it will include automatic scheduling, reminders, overall progress tracking, and more. It will be a couple months before we're able to finish the full feature set, but stay tuned! We think it will be very helpful.
I would love to see stats for how many verses that I have memorized and the ones that I should review.
