Developed and delivered a Track Rating System for the mixxxdj/mixxx repository, enabling users to assign 1-5 star ratings to tracks directly through the user interface. The implementation involved designing new UI controls, integrating the rating logic with the existing playback and library features, and establishing a data model for storing user feedback. Controller bindings were added to allow hardware-based rating assignment, supporting more nuanced playlist curation and personalization. The work was completed using C++ with a focus on control systems and UI development, laying a technical foundation for enhanced user engagement, analytics, and future recommendation features within the application.
