Node management: Create siblings and children with single keystrokes, copy/paste entire branches, and undo changes instantly
Flexible editing: Edit node titles with intuitive commands, append text to existing nodes, and maintain complex hierarchies effortlessly
Visual organization: Toggle node visibility, collapse/expand sections at any depth, focus on specific branches, and adjust spacing and width to suit your needs
Ranking system: Vote on ideas with positive and negative points, or use star ratings to prioritize options during group workshops
Search functionality: Find phrases across your entire map and navigate between results
Export options: Save as HTML files or export text maps directly to clipboard
Customizable: Configure colors, key bindings, clipboard behavior, and auto-save settings through a simple config file
Marks and symbols: Add checkmarks, crosses, numbers, and stars to track status and priority

The tool uses vim-style navigation (hjkl keys) combined with intuitive mnemonics, making it accessible to both terminal veterans and newcomers. Whether you're brainstorming alone or facilitating group decision-making, h-m-m provides the speed and flexibility to keep pace with your thinking.
