Create, edit, and organize hierarchical mind maps with an intuitive interface featuring tabbed editing, multiple layout styles, undo/redo, and theme support.\n\n## Screenshots\n\n![Screenshot](./img/AutoLayout.gif)\n![Screenshot](./img/StartPage.png)\n![Screenshot](./img/LightTheme.png)\n![Screenshot](./img/DarkTheme.png)\n\n## Features\n\n- **Tabbed Editing** - Work on multiple mind maps simultaneously with drag-to-reorder tabs\n- **Multiple Layouts** - Bilateral (balanced left/right), Top-Down (org chart), and Right-Tree (project plan) layouts\n- **Auto Layout** - Automatically arrange nodes with `Ctrl+L`\n- **Undo/Redo** - Full command-based undo/redo for add, remove, edit, and move operations\n- **Drag \u0026 Drop** - Reposition nodes and subtrees by dragging\n- **File I/O** - Save and load mind maps in `.ymind` (JSON) format\n- **Export** - Export to PNG (2x scaling), SVG, PDF, plain text, or Markdown\n- **Import** - Import mind maps from indented text files\n- **Templates** - Start from built-in templates (Mind Map, Org Chart, Project Plan), load custom templates from JSON, or start with a blank canvas\n- **Themes** - Light and Dark mode with system theme detection\n- **Auto-Save** - Configurable automatic saving with 1-5 minute intervals\n- **Outline Sidebar** - Tree-based outline view for quick navigation\n- **Settings** - Configurable theme, fonts, auto-save, and editor preferences\n- **Zoom \u0026 Pan** - Scroll wheel zoom, fit-to-view, and middle/right-click panning\n- **Keyboard-Driven** - Comprehensive keyboard shortcuts for efficient editing\n\n## Building\n\n### Prerequisites\n\n- C++17 compiler (GCC, Clang, or MSVC)\n- CMake 3.16+\n- Qt6 (Widgets, Svg, PrintSupport)\n\n### Build Instructions\n\n```bash\nmkdir build \u0026\u0026 cd build\ncmake ..\nmake\n./ymind\n```\n\n### Build Options\n\n```bash\n# Build with unit tests\ncmake .. -DBUILD_TESTING=ON\n\n# Build with clang-tidy static analysis\ncmake .. -DENABLE_CLANG_TIDY=ON\n\n# Run tests\nctest --output-on-failure\n```\n\n## Keyboard Shortcuts\n\n| Shortcut            | Action               |\n| ------------------- | -------------------- |\n| `Enter`             | Add child node       |\n| `Ctrl+Enter`        | Add sibling node     |\n| `Del`               | Delete selected node |\n| `F2` / Double-click | Edit node text       |\n| `Ctrl+L`            | Auto layout          |\n| `Ctrl+T`            | New tab              |\n| `Ctrl+W`            | Close tab            |\n| `Ctrl+N`            | New file             |\n| `Ctrl+O`            | Open file            |\n| `Ctrl+S`            | Save                 |\n| `Ctrl+Shift+S`      | Save as              |\n| `Ctrl+Z`            | Undo                 |\n| `Ctrl+Y`            | Redo                 |\n| `Ctrl++`            | Zoom in              |\n| `Ctrl+-`            | Zoom out             |\n| `Ctrl+0`            | Fit to view          |\n| `Ctrl+,`            | Settings             |\n| Scroll wheel        | Zoom                 |\n| Middle/Right-drag   | Pan                  |\n\n## Project Structure\n\n```\nymind/\n├── CMakeLists.txt\n├── .clang-tidy             # clang-tidy configuration\n├── LICENSE\n├── README.md\n├── resources/\n│   ├── resources.qrc\n│   └── theme.qss           # QSS stylesheet template\n├── tests/                   # Qt Test unit tests\n│   ├── CMakeLists.txt\n│   ├── tst_TemplateDescriptor.cpp\n│   ├── tst_LayoutStyle.cpp\n│   ├── tst_TemplateRegistry.cpp\n│   ├── tst_LayoutAlgorithmRegistry.cpp\n│   ├── tst_AppSettings.cpp\n│   └── tst_MindMapSceneSerialization.cpp\n└── src/\n    ├── main.cpp\n    ├── core/                # Application infrastructure\n    │   ├── MainWindow       # Main window, menus, toolbar, auto-save\n    │   ├── FileManager      # File I/O, export, and import\n    │   ├── Commands         # Undo/redo commands (add, remove, edit, move)\n    │   ├── AppSettings      # Settings singleton (theme, auto-save, fonts)\n    │   ├── SettingsDialog   # Settings dialog UI\n    │   ├── TemplateDescriptor  # Template data structures and JSON serialization\n    │   └── TemplateRegistry    # Template registration and lookup\n    ├── scene/               # Graphics scene items\n    │   ├── MindMapScene     # Scene managing nodes, edges, serialization\n    │   ├── MindMapView      # View with zoom, pan, and grid background\n    │   ├── NodeItem         # Node graphics item with floating shadow\n    │   └── EdgeItem         # Curved bezier edge connector\n    ├── layout/              # Auto-layout algorithms\n    │   ├── ILayoutAlgorithm       # Abstract algorithm interface\n    │   ├── LayoutAlgorithmBase    # Shared measure/place/refine phases\n    │   ├── BilateralLayout        # Left/right balanced tree\n    │   ├── TopDownLayout          # Top-down org chart\n    │   ├── RightTreeLayout        # Right-expanding tree\n    │   ├── LayoutAlgorithmRegistry  # Algorithm registry singleton\n    │   ├── LayoutEngine           # Static layout facade\n    │   └── LayoutStyle            # Enum and name conversions\n    └── ui/                  # Widgets and theming\n        ├── ThemeManager     # Theme color palette singleton\n        ├── StyleSheetGenerator  # CSS stylesheet generation\n        ├── TabManager       # Tab bar and content stack management\n        ├── StartPage        # Template gallery start page\n        ├── OutlineWidget    # Tree-based outline sidebar\n        └── IconFactory      # SVG icon and preview generation\n```\n\n## License\n\nThis project is licensed under the Apache License 2.0.
