- allows separate review order for different decks - makes new card and rev card handling consistent - for users who find it confusing to have cards from different decks mixed in and thus click on each deck in turn, they can now just select the parent deck and have it work as expected - for users who want their cards mixed together randomly, they can keep the cards in a single deck
