The Markdown Hijacker plugin enables seamless synchronization between your vault and external folders, supporting markdown and other user defined file types. It allows one-way or bidirectional syncs, with real-time monitoring and offline change detection to ensure files stay updated even if edited outside the app. You can map multiple folder pairs, control how deletions are handled, and finetune inclusion based on subfolders, file extensions, or hidden files. Sync status is visible in the status bar, and metadata is managed via frontmatter. This setup is especially useful for integrating existing notes, working across devices, or collaborating with other tools without being locked into a single workspace.
