Worked on the LimeSurvey/LimeSurvey repository to deliver a comprehensive refresh of the admin themes UI, focusing on resolving layout inconsistencies and improving usability across devices. Addressed a persistent issue with dropZone width stretching by rebuilding the layout using JavaScript and front end development best practices, ensuring consistent rendering at various breakpoints. Additionally, fixed a responsive image overlap bug by refining layout handling for different aspect ratios, which enhanced the reliability of the admin interface. All changes were implemented with a strong emphasis on maintainability and traceability, leveraging UI/UX design principles to create a more robust and user-friendly experience.
