You can effectively put your Do Later recipes into folders by categorizing the recipes in there. So for example if you categorize some as Dinner Parties, some as Everynight Dinners (categories you would set up in Classifications), then when you come to search, use Advanced search, select the category you want and search in Do Laters. You are now only looking in that "folder" of your Do Laters. Let me know if this isn't clear.
