Order the "Playlists" columns by updated date
What is the problem you are facing?
I think it would be nice to order the playlist column by recent changes. That way users will see new playlist more often, and see which one are actively updated for new songs. Could be better for discoveries and showing implications from other users on the instance.
What are the possible drawbacks or issues with the requested changes?
I don't think there would be any issue.
What could be an improvement of this feature are different order types, like "name", "last updated", "last created", "largest", or such.
