The metatemplates plugin enhances the use of YAML frontmatter to create dynamic, structured templates for note generation in Obsidian. It serves as a replacement for the core Templates plugin, offering additional flexibility by utilizing type, nameFormat, and destFolder properties in the frontmatter. Notes created from templates can have dynamic filenames and destinations, and automatically update based on changes to frontmatter attributes. The plugin supports date and time placeholders for easier note creation. Its features streamline workflows by ensuring consistent note organization and content generation.
