Being able to generate quizzes based on topics/tags rather than individual sources, and have better organization in the daily review section. Currently, the quiz feature feels too tied to individual sources. If I load 50 sources for research on a single subject, I don't want to be quizzed on one specific source—I want to test my knowledge on the topic as a whole. Key enhancements requested: Topic/Tag-Based Quizzes: The ability to select a tag or topic and have Recall pull information from all related cards to generate a comprehensive quiz. Interactive Quiz Flow: A chat or prompt interface where I can say, "I want to learn more about [Topic]" or "Give me 15 questions on [Tag]," and it generates a custom quiz on the fly from my knowledge base. Categorized Daily Reviews: Split the daily quiz/review section into "Newer Material" (recently added cards) and "Older Material" (spaced repetition for past research). Making the review section more interactive and topic-focused would make it an incredibly powerful tool for synthesizing research!
