The Link Maintainer plugin helps users manage and maintain block references and internal links within Obsidian, especially when splitting or reorganizing notes. It automatically updates references in markdown notes and canvas files, ensuring that links to block IDs remain accurate even after content is moved to a new note. This eliminates the need for manual updates to block references, saving users significant time and effort. The plugin provides a preview of all changes before they are applied, allowing users to review and confirm updates, ensuring a secure and controlled process. It is particularly useful for those working with large notes or managing a complex knowledge base, making it easy to keep cross-note references intact while restructuring content.
