Developed a user feedback notification feature for the Hypertopic/HyperGlosae repository, focusing on enhancing the Split into Passages workflow. The work involved implementing a success toast using React and JavaScript, which appears upon completion of the split action to provide immediate confirmation to users. This approach addressed the requirement to reduce ambiguity and support faster user decisions by establishing a clear notification pattern. The feature was directly linked to tracked requirements and issues, ensuring traceability within the codebase. The contribution demonstrated attention to user experience in frontend development, with an emphasis on actionable feedback and maintainable notification logic.
