The Edit History plugin allows users to maintain a comprehensive edit history for their notes in Obsidian. Each edit is saved in a dedicated history file, enabling users to browse, diff, or copy previous versions of their notes. The plugin supports efficient, compressed diff storage, making it possible to manage large histories without significant storage overhead. Users can limit the frequency, size, and age of stored edits for better control. Edit history files are automatically updated when notes are renamed or deleted, and they can be managed externally for backup or deletion. The plugin also includes manual save options and a convenient interface for reviewing and copying changes.
