The Object Oriented Thinking plugin introduces inheritance like behaviour to notes by allowing one note to extend another using frontmatter properties. It provides utility methods for querying and determining hierarchical relationships between notes, enabling advanced workflows where child notes can inherit attributes from parent notes. Developers can leverage these methods in Dataview queries or custom scripts to build dynamic, object-oriented structures within their vault. This makes it particularly useful for organising complex systems like task hierarchies, documentation, or knowledge bases.
