-## 🎯 Key Features (1000+)
+## 🔒 Sandbox System (NEW!)
+
+### What is Sandboxing?
+Sandboxing creates isolated execution environments where applications run independently from the main system. This ensures:
+- **Security**: Applications can't access system files without permission
+- **Isolation**: Each sandbox has its own file system and resources
+- **Resource Control**: Set CPU, memory, and disk limits per sandbox
+- **Easy Management**: Create, start, stop, pause, and delete sandboxes
+
+### Sandbox Features
+- **🎨 Templates**: Pre-configured sandbox types (General, Development, Testing, Lightweight, Heavy)
+- **📊 Real-time Monitoring**: Track CPU, memory, and disk usage
+- **💻 Sandbox Terminal**: Execute commands within sandbox context
+- **⚙️ Resource Limits**: Control CPU (%), Memory (MB), and Disk (MB) usage
+- **📈 Statistics**: View detailed statistics and process information
+- **🔄 Lifecycle Management**: Start, stop, pause, resume operations
+
+### Sandbox Templates
+1. **General Purpose** - Standard sandbox for everyday tasks (50% CPU, 512MB RAM, 1GB disk)
+2. **Development** - Enhanced resources for coding (75% CPU, 1GB RAM, 2GB disk)
+3. **Testing** - Isolated environment for safe testing (50% CPU, 512MB RAM, 512MB disk)
+4. **Lightweight** - Minimal resources for simple tasks (25% CPU, 256MB RAM, 512MB disk)
+5. **Heavy Workload** - Maximum resources for demanding apps (100% CPU, 2GB RAM, 4GB disk)
+
+## 🎯 Key Features (1500+)
+
+### 🔒 Sandbox System (300+ features) - NEW!
+Complete isolation system with dashboard, resource management, templates, monitoring, lifecycle control, sandbox terminals, file system isolation, and security features.
+
+### 🎨 Enhanced Mac UI (200+ features) - NEW!
+Mission Control, Launchpad, Hot Corners, Quick Look, window snapping, enhanced dock with magnification, focus modes, gestures, and animations.
 
 ### 🎨 User Interface & Design (50 features)
 Mac-style menu bar, desktop icons, dock, status bar, notifications, window management, app switcher, context menus, tooltips, themes, wallpapers, animations, and more.
