Several of my challenges have multiple books attached to a single prompt. Because I'm not sure which one I'll read to complete the prompt. I've tried to go back in and remove the extra books, to reflect which one I actually read, but it is a painstakingly slow process. And after removing the book, I can't just return to the challenge page. I have to start from scratch and find my way back to the challenge all over again.

I'd love to see a feature that simplifies this process, perhaps letting you quickly remove multiple books at once from a challenge. Or even a back button that can return me to the challenge page.
