The At People plugin brings a familiar @-mention syntax to Obsidian, making it easier to create links to people's profiles stored as markdown files. By typing the @ symbol and selecting a suggestion, the plugin generates a link to the relevant file, such as [[@Rich Hickey]]. It offers customization options, including the ability to organize people into folders, adjust the link structure, and even group people by their last name. The plugin enhances note-taking by allowing quick references to individuals and works seamlessly with your existing vault organization.
