SimpleMindmap

SimpleMindmap is an intuitive and lightweight web application for creating mind maps. It offers a simple and efficient user interface to visually organize your ideas.

• Create and edit nodes with custom text
• Drag and drop nodes to organize your mind map
• Connect nodes to show relationships
• Add child nodes to create hierarchies
• Multi-select nodes for bulk actions
• Copy, cut, and paste nodes
• Undo and redo actions
• Zoom in and out of the mind map
• Pan across the mind map
• Custom color picker for nodes
• Calculator nodes for simple arithmetic operations
• Backup and restore functionality

1. Open the HTML file in a modern web browser.
2. Use the "Add Node" button to create new root nodes.
3. Click the "+" button on existing nodes to add child nodes.
4. Double-click a node to edit its content.
5. Drag nodes to reposition them.
6. Use the "Connect Mode" to create connections between nodes.
7. Right-click on nodes or connections to delete them.
8. Use the color picker to change node colors.
9. Use keyboard shortcuts (Ctrl+C, Ctrl+X, Ctrl+V) for copy, cut, and paste operations.
10. Click "Add Formula" to create a calculator node.

Calculator nodes allow you to perform simple arithmetic calculations. Here are some examples of formulas you can use:

• Simple addition: 5 + 3
• Combination of operations: (10 + 5) * 2 - 8 / 4
• Using decimals: 3.14 * 2 + 1.5

Note: The calculator does not support advanced mathematical functions or variables.

• Use the "Backup" button to download a JSON file of your current mind map.
• Use the "Restore" button to upload a previously saved JSON file and restore your mind map.

SimpleMindmap works best in modern web browsers such as Chrome, Firefox, Safari, and Edge.

• Ctrl + C: Copy selected nodes
