The Repeat plugin enables spaced or periodic repetition of notes using natural language scheduling. By adding a `repeat` property to a note's frontmatter, users can schedule reviews at intervals like 'every week' or 'spaced every 3 days'. A dedicated Repeat view displays due notes and lets you update schedules with a single click. Notes can also be marked as hidden to obscure their contents until review, supporting one-sided flashcard-style use. The plugin keeps all scheduling metadata within the note itself, making it easy to edit or review manually.
