The Simple Note Review plugin enables users to rediscover and review notes in Obsidian without adhering to a rigid spaced repetition schedule. By creating customizable note sets based on tags, folders, or DataviewJS queries, users can organize notes into queues for review. Notes can be reviewed sequentially or randomly, and review queues can be reset to start fresh. The plugin also allows users to adjust the review frequency of individual notes or exclude them from reviews entirely.
