folders or "list groups" feature for community lists; and community list custom "cover art"
I plan to post many community lists on my profile as part of my "Make DC Epic" project (see here: https://leagueofcomicgeeks.com/profile/joeyhines). For the time being, when I only have a few lists, the pin function is a reasonable way for me to sort them. However, as I add more (planning on at least 72 lists, possibly more to come) it will get unwieldy for a visiting user to scroll through that many lists on my profile, & also for me to arrange 72+ items by pinning. At least a drag & drop sort option for the list themselves (like is possible for the issues within the lists) would be better. What would be best is if I could create folders or groups or a "list series", i.e. one for my "Batman Bronze Age" lists, one for my "Batman Post-Crisis" lists, one for my "Legion of Super-Heroes Post-Crisis" lists, etc.
Related idea: my lists are based on hypothetical collected editions & I create front & back cover art for them. It would be really nice to be able to upload custom art for each community list, similar to the way Spotify users can upload a custom image for their created playlists, different from the default art of whatever comics are included in the list.
