Developed a user feedback enhancement for the gaelpoette/COURS_COLLAB_2024 repository by implementing an End-of-Calculation Indicator using Python scripting. This feature introduced a simple print statement to notify users when calculations complete, improving user experience without altering the core calculation logic. The approach prioritized non-intrusive integration, ensuring existing workflows remained unaffected and the codebase stayed stable. All changes were delivered in a single, well-documented commit, supporting traceability and maintainability. No major bugs were addressed during this period, and the system’s stability was preserved. The work lays a foundation for future user feedback features and additional status indicators within the project.
