Especially because of challenges that have a large number of prompts, I'd like a way to search for a specific prompt in the challenge. E.g., in a "read the world" challenge, I'd have to scroll a long time to reach a particular prompt out of hundreds, and the app often freezes up with so much scrolling on one challenge. Moreover, sometimes when I select a prompt and then go back to the list of challenge prompts, I'm moved back up to the top of the list and have to scroll all the way down again. All this to say, I'd like a way to search through challenge prompts on the challenge page, like how you can search through challenge prompts when you go through the options to add a specific book to a challenge starting from the book page!
