Miller Columns Plugin
Provides a compact miller column visualization for nested lists.
Hierarchy defaults to a collapsed state, minimizing cognitive load. Includes keyboard navigation and direct element mutation (create, delete, toggle).
Mechanism
Append #miller-view to any list then switch to reader mode. For example:
- Project #miller-view
- Design
- Wireframes
- Tokens
- Build
- Parser
- Renderer
Any changes done in the miller view apply in real time to the original markdown.
