The Tier List plugin allows users to visually rank items in Obsidian by rendering nested lists as customizable tier lists. It supports manual sorting, enabling flexible ranking of items like movies, games, or projects without assigning numerical ratings. The plugin integrates images from both internal and external sources, including frontmatter-defined covers, to enhance visual organization. Users can interact with tier lists in both editing and reading modes, with quick ranking options via right-click menus and drag-and-drop functionality.
