Sort Completed Challenges

I’d really like it if we could sort completed challenges, at least by column header (i.e. rank and completed date). I’d also like to delete old ones if I want and purge the list from time to time.

I’d like to see this too, or at least move completed challenges to the bottom of the my list of challenges. I don’t mind them staying on my list because they show what I’ve accomplished, but it would be nice to not have them mixed in with my active ones
