The Cluster plugin streamlines the process of organizing notes into hierarchical clusters, making navigation and relationship-building easier in Obsidian. It is especially designed for mobile devices but works seamlessly on PCs as well. The plugin allows users to create parent-child hierarchies, generate linked notes (sons and brothers), and manage orphan notes effectively. Notes are automatically tagged and given properties to support search and visualization in the graph view. Features include intuitive folder management, ribbon and in-note buttons for easy navigation, and commands to create or delete clusters and their associated notes. This structure aids in maintaining clarity and consistency, particularly for users dealing with large note collections.
