The Index Notes plugin for Obsidian streamlines the management of large knowledge bases by automating the creation of index blocks within notes. These indices are generated based on hierarchical tags and updated dynamically as tags are added or modified. The plugin creates a nested list of links, reflecting the tag hierarchy in both the note and the graph view. Users can leverage additional features like creating meta-indices, setting priority tags to highlight specific notes, and displaying titles from metadata for better clarity. The plugin also includes a command and ribbon icon for quickly creating new notes with inherited metadata and location. With flexible tag-based organization, it eliminates the need for rigid folder structures and makes note indexing more efficient.
