                        ### Common Issues:
                        1. **Syntax Errors**: Check your Python code for any syntax issues
                        2. **Missing Scene Class**: Ensure your code contains a scene class that extends Scene
                        3. **High Resolution Issues**: Try a lower quality preset for complex animations
                        4. **Memory Issues**: For 4K animations, reduce complexity or try again
                        5. **Format Issues**: Some formats require specific Manim configurations
                        6. **GIF Generation**: If GIF doesn't work, try MP4 and we'll convert it automatically
                        
                        ### Example Code:

                - Animation will autoplay when clicked
                - Add detailed explanations in notes section
                
                **Interactive HTML**
                - Perfect for websites and online learning platforms
                - Students can control playback speed and navigation
                - Mobile-friendly for learning on any device
                
                **Explanation Sequence**
                - Ideal for printed materials and study guides
                - Use ## headers to mark different explanation sections
                - Each section will be paired with a key frame

            ### Python Script Runner Tips
            
            **What can I run?**
            - Any Python code that doesn't require direct UI interaction
            - Libraries like Matplotlib, NumPy, Pandas, SciPy, etc.
            - Data processing and visualization code
            - Scripts that ask for user input (now supported!)
            
            **What can't I run?**
            - Streamlit, Gradio, Dash, or other web UIs
            - Long-running operations (timeout will occur)
            - Code that requires file access outside the temporary environment
            
            **Working with visualizations:**
            - All Matplotlib/Seaborn plots will be automatically captured
            - Pandas DataFrames are detected and displayed as tables
            - Use `print()` to show text output
            
            **Handling user input:**
            - The app detects input() calls and automatically creates text fields
            - Input values you provide will be passed to the script when it runs
            - Type conversion (like int(), float()) is preserved
            
            **Adding to animations:**
            - Charts and plots can be directly added to your Manim animations
            - Generated images will be properly scaled for your animation
            - Perfect for educational content combining data and animations

            ### C/C++ Runner Tips
            
            **Compilation Options:**
            - Choose the appropriate compiler based on your platform
            - Select the C++ standard version for your code
            - Optimization levels affect performance and debugging
            
            **Library Support:**
            - Common libraries like Eigen, OpenCV, and Boost are supported
            - Add custom include paths and library paths as needed
            - Use the library detection feature to find installed libraries
            
            **Input/Output:**
            - Standard input/output (cin/cout) is fully supported
            - File I/O works within the execution directory
            - For interactive programs, provide input values in advance
            
            **Debugging:**
            - Set breakpoints at specific line numbers
            - Watch variables to track their values
            - Debug with GDB for detailed analysis
            
            **Project Management:**
            - Create multi-file projects with headers and source files
            - Generate CMakeLists.txt for complex projects
            - Download project files as a ZIP archive
            
            **Images and Visualization:**
            - Generate images in PPM, PNG, JPG formats
            - Use OpenCV for more advanced image processing
            - All generated images can be used in Manim animations
            
            **Manim Integration:**
            - Create algorithm visualizations from C++ code
            - Import C++ generated images into Manim scenes
            - Visualize data structures and memory models
            
            **Performance:**
            - Use release mode for best performance
            - Profile your code to identify bottlenecks
            - C++ is ideal for computationally intensive tasks
