Hi,I've been using Mnemosyne since yesterday to review the vocabulary from NPCR.The deck contains a lot of duplicates (738) as a lot of the extra vocabulary from a lesson becomes the regular vocabulary in later lessons of the textbook. Using the "find duplicates" option I have tagged all the duplicates as "DUPLICATE".How can I now the review of i.e. the cards with the tag 'NPCR 2' while excluding the cards with the tag 'DUPLICATE'?
