I am very much addicted to this app. It's relaxing and has many great pics and categories to choose from, with new stuff added daily. I've colored over 900 of them, and even purchased the ad free version (worth it). My one request and critique is that the panel of colors needs to be updated with a better/faster way to scroll. Getting from #1 to #100+ and back again is a chore. An optional double row color panel, or even a quick scroll bar would help greatly.
