The Watched-Metadata plugin enhances note management in Obsidian by monitoring changes in metadata fields and triggering specific actions. It offers two primary functionalities: header replacement and command execution. Users can configure header groups to automatically replace specified headers with metadata values or set up command groups to execute predefined commands when metadata changes. These features make it easier to keep notes dynamic and actionable, aligning with real-time updates. The plugin's customizable settings provide a user-friendly interface to manage and automate tasks based on metadata changes.
