On the mobile app (I have an iPhone 5S), it would be awesome if the completed Power-Up's/Quests/Battles looked more exciting rather than having just a small, grey check mark (that is hard to see) or just simply greyed out. What if they were greyed out (for contrast against other non-completed ones) and then had a big start overtop of them as well, instead of the grey check marks? And also making the check marks next to the categories (when you finish 3/3 or whatever) more than just grey.
This is an awesome app! Thank you so much!!!
