Grouping Lists

All our lists under "Custom Lists" are displayed together.

I think it would be great if we could sort the lists by "Titles," "People," and "Voting." It would also be nice to have a way to group lists. If I have 20 lists, I always have to search for the one I want. It would be helpful to have sets of lists, like "Watched in ..." lists or "Dramas from ..." lists.
