            ## 🔧 Tips for Large Scripts
            
            **Organization:**
            1. **Break down large scripts** into functions and classes
            2. **Add comments** to help navigate your code
            3. **Use consistent indentation** for readability
            4. **Group imports at the top** of your script
            
            **Performance:**
            1. **Minimize dependencies** for faster compilation
            2. **Avoid complex nested structures** when possible
            3. **Use efficient algorithms** for better runtime performance
            4. **Test smaller parts** before compiling the full script
            
            **Error Handling:**
            1. **Add try/except blocks** for robust error handling
            2. **Handle user input gracefully** with validation
            3. **Include network error handling** (automatically added)
            4. **Provide clear error messages** for users
            
            ## 🌐 Network Error Handling for Large Scripts
            
            Even with large scripts, the network error handling remains effective:
            ```python
            # Automatically added to all compiled scripts
            try:
                # Your network operations
                response = urllib.request.urlopen('https://api.example.com')
            except urllib.error.URLError as e:
                if 'could not resolve host' in str(e.reason).lower():
                    print("✓ Network error detected and handled gracefully")
                    sys.exit(6)  # Consistent exit code
            ```
            
            ## 📊 Code Editor Features
            
            **Enhanced Layout:**
            - **50 lines visible** by default (vs 20-28 in typical editors)
            - **Auto-expansion** up to 100+ lines as needed
            - **Scrollable interface** for unlimited script size
            - **Syntax highlighting** for Python code
            - **Line numbers** for easy navigation
            
            **Management Tools:**
            - **File upload support** for existing scripts
            - **One-click clearing** for starting fresh
            - **Code formatting** (if black is available)
            - **Editor expansion** for very large scripts
            - **File information display** when uploading
            
            ## 🚀 Best Practices for Large Scripts
            
            **Before Compilation:**
            1. **Test your script locally** to ensure it works
            2. **Verify all imports** are included in requirements.txt
            3. **Check for syntax errors** using the editor
            4. **Consider script size** - larger scripts take longer to compile
            
            **During Compilation:**
            1. **Monitor progress** through the real-time logs
            2. **Watch for errors** in the compilation output
            3. **Be patient** - large scripts need more time
            4. **Check requirements** if compilation fails
            
            **After Compilation:**
            1. **Download the binary** immediately
            2. **Test on a clean system** if possible
            3. **Verify network error handling** works
            4. **Document any dependencies** for users
            
            ## ⚠️ Limitations and Workarounds
            
            **File Size Limits:**
            - Gradio may have upload size limits
            - **Workaround**: Break very large scripts into modules
            
            **Memory Usage:**
            - Large scripts use more compilation memory
            - **Workaround**: Use "Portable Binary" mode for lighter builds
            
            **Compilation Time:**
            - Large scripts take longer to compile
            - **Workaround**: Test with smaller versions first
