• UI Module: Rendering, menus, interface elements
• Drawing Module: Graphics operations, tools, algorithms
• Clean Interfaces: Well-defined APIs between modules

Professional Patterns

• Singleton State: Centralized application state
• Namespace Organization: Clear module boundaries
• Event-Driven: Proper message handling architecture
• Separation of Concerns: Logic separated from presentation

🔧 Development

Build System

The project uses a professional modular build system:

# If make is available:
make all         # Build application
make debug       # Debug build  
make release     # Optimized build
make structure   # Show project layout
make help        # Available commands

# Direct compilation:
# Compile each module to object files, then link

Testing

Comprehensive test suite with professional framework:

• Unit tests for all major components
• Integration tests for full application
• Performance and stress testing
• Automated test runner

📚 Documentation

• REFACTORING.md - Detailed refactoring guide
• TESTING.md - Test suite documentation
• Header Files - Comprehensive API documentation

🎯 Key Improvements

Before Refactoring

• ❌ Single monolithic 1000+ line file
• ❌ Mixed concerns and responsibilities
• ❌ Difficult to maintain and extend
• ❌ Hard to test individual components

After Refactoring

• ✅ Modular Architecture - Clean separation of concerns
• ✅ Professional Structure - Industry-standard organization
• ✅ Maintainable Code - Easy to understand and modify
• ✅ Testable Components - Individual module testing
• ✅ Scalable Design - Easy to extend with new features
• ✅ Team-Ready - Multiple developers can work simultaneously
