Hi CIJ Team,
I just wanted to take a moment to thank you for adding the feature to sort videos by difficulty level. I can imagine that it took a lot of time, having to analyze all of the videos that have been made. But as someone who has watched all of the total beginner/beginner videos from oldest to newest a couple of times, I can say that my latest challenge of watching them all sorted by difficulty level is going much smoother, as some videos were noticeably easier/harder than other in the old sort order.
Feel free to delete this post, but I am really enjoying this new feature and wanted to pass that message on 
I’m happy to hear it’s working out much better for you
