Would love to be able to filter/sort Reading Challenges, not only while browsing new challenges, but also on my own profile or while looking at challenges I’ve already joined. As an example, having the option to sort by challenge soonest to end would be super helpful! And having the start/finish date displayed somewhere on the thumbnail(?) like the number of prompts completed would also be nice.
Also, I join ongoing/perpetual challenges whenever they seem even a little interesting because I don’t want to lose track of them, though I don’t always want to start them immediately. Would be nice to have a bookmark (haha) option to revisit interesting challenges on a separate page so challenges I’m not actively trying to complete don't overtake my profile or the Reading Challenges page.
Also had the thought that pinning challenges so they appear at the top of the list could be useful! Like if someone is prioritizing a challenge because it's part of a book club, a social media thing, or just because it's the one they're focusing on right now!
