+## Session: 2025-03-19 - Enhanced Report Management UI
+
+### Overview
+Implemented significant improvements to the report management UI, focusing on checkbox functionality and visual aesthetics while ensuring proper integration with backend operations.
+
+### Key Activities
+1. **Improved Checkbox Display and Organization**:
+   - Implemented a custom HTML/JavaScript solution for the checkbox interface
+   - Created a visually appealing single-column layout for better readability
+   - Added proper styling with dark theme to match the overall UI aesthetics
+   - Implemented scrolling capability for handling long lists of reports
+
+2. **Added Check/Uncheck All Functionality**:
+   - Implemented a "Check/Uncheck All" checkbox at the top of the list
+   - Created JavaScript functions to handle the toggle behavior client-side
+   - Ensured all checkbox state changes are properly tracked
+
+3. **Enhanced Backend Integration**:
+   - Implemented JSON-based communication between the UI and backend
+   - Added robust error handling for JSON parsing to prevent crashes
+   - Improved logging to track user selections and aide debugging
+   - Made the download and delete handlers more resilient to input errors
+
+4. **UI Styling Enhancements**:
+   - Changed the container background to dark theme to match the rest of the UI

+   - Added proper borders, padding, and spacing for visual consistency
+   - Ensured the UI is responsive with appropriate scrolling behavior
+
+### Insights
+- Custom HTML/JavaScript solutions provide more control over UI layout than Gradio's built-in components
+- Dark themed UI elements create a more consistent and professional look
+- Robust error handling is critical for UI components that process user input
+- Detailed logging helps identify and fix issues in interactive elements
+
+### Challenges
+- Gradio's default checkbox layout wasn't conducive to a single-column display
+- JSON parsing between JavaScript and Python required careful error handling
+- Ensuring visual consistency with the rest of the application
+- Maintaining proper event handler connections when switching to custom HTML
+
+### Next Steps
+1. Gather user feedback on the improved checkbox interface
+2. Consider adding filtering capabilities to help manage large report lists
+3. Explore the possibility of batch operations for report management
