The MathLinks plugin allows Obsidian users to integrate MathJax equations into their note links, providing enhanced visualization and readability. By assigning MathJax expressions to note links through YAML frontmatter, users can render these equations dynamically in live-preview, reading mode, and canvases. The plugin supports customization with templates for automated link generation, compatibility with Dataview and Extended MathJax, and rendering for block and heading links. MathLinks also includes settings for exclusions and preferences for source mode rendering, making it a powerful tool for managing math-rich content.
