## 🛠️ Customization Guide

### Adding New Themes
```java
themes.put("ThemeName", new Color[]{
    new Color(R, G, B),    // Zero/Default color
    new Color(R, G, B),    // Positive color  
    new Color(R, G, B)     // Negative color
});
```

### Extending Features
- **New Counters**: Add to counters Map
- **Custom Sounds**: Modify createBeepSound() method
- **Additional Analytics**: Extend updateAnalytics() method
- **New Export Formats**: Add to exportStatistics() method

## 🐛 Troubleshooting

### Common Issues
1. **Compilation Errors**: Ensure JDK 8+ is installed
2. **Sound Issues**: Check system audio configuration
3. **File Permissions**: Ensure write access to application directory
4. **System Tray**: Not supported on all platforms
5. **Memory Usage**: Large history may require heap size adjustment

### Solutions
- **Java Version**: `java -version` to verify installation
- **Compilation**: `javac -version` to check compiler
- **Permissions**: Run from user directory with write access
- **Memory**: Use `-Xmx512m` for larger history sets
