The KoReader Highlight Importer plugin enables seamless integration between KoReader and Obsidian by importing highlights and annotations directly into your vault. It scans .sdr directories, parses metadata files, and organizes highlights into Markdown notes with YAML frontmatter for easy reference. Users can customize settings like the mount point, target folder for highlights, and file type filters. With options for scanning and importing, it provides flexibility and automation for managing reading highlights, making it a valuable tool for avid readers and researchers.
