Nicolai Berwald developed a safety feature for the AAU-P5-Moodle/moodle-1 repository, focusing on the live quiz editing workflow. He implemented a confirmation dialog to prevent accidental data loss when discarding edits to quiz questions, addressing a key risk for educators. The work involved targeted UI refinements on both teacher and student index pages to support the new confirmation flow and enhance usability. Nicolai integrated these changes into the build pipeline using grunt, ensuring maintainable deployment and traceability. His contributions leveraged front end development skills with JavaScript and PHP, delivering a focused, well-integrated feature without introducing new defects during the period.
