The Tag Tactician plugin simplifies bulk editing of frontmatter tags in Obsidian, allowing users to add or remove tags across multiple notes simultaneously. It provides a preview of changes before applying them and offers selective updates to ensure precise tag management. The plugin also features a Related Notes view, which helps users find notes with similar tags, titles, or paths based on customizable weighting. Additionally, it includes a Tag Navigation sidebar that organizes notes using a hierarchical tag structure, functioning as an alternative to traditional folders. With options for customizing tag formats and filtering related notes, this plugin enhances tag-based organization and discovery within Obsidian.
