The Related Notes Finder plugin is a useful Obsidian tool that helps you discover relevant notes in your vault. With this plugin, you can search for notes whose titles include any word from the active note, and have links to those related notes appended to the original note. The plugin offers customization options, such as filtering out common words like "the" or setting a minimum number of characters for search terms. This plugin is perfect for users who want to quickly find connections between their notes and explore new ideas.
