The Tag Page plugin enhances Obsidian by allowing users to create dedicated Markdown pages for individual tags. These tag pages are automatically populated with content based on the tag's usage throughout the vault. Users can refresh tag page content with a single click and customize the directory where these pages are stored. Additional features include the ability to include lines containing the tag, sub-items, and flexible frontmatter queries to tailor tag page organization. Nested tags can also be managed efficiently, making it easier to organize and navigate tag-related content.
