Currently, custom lists with shows can only be sorted by author or alphabetical order, and you can't switch between the two sort orders without going in to edit the list.
It would help make custom lists with shows more useful if there was an option to view the list using the same column headers as in the Watchlist (Title, Country, Year, Type, Score, Progress, etc.). That way, you could click on the column headers to sort the custom list just as you do with the Watchlist.
Since a view of this type already exists with the Watchlist, it doesn't seem like too big of a stretch to also provide the same view for custom lists.
