Lintu Su worked on the Class-Widgets/Class-Widgets repository, delivering a robust plugin-driven desktop application for class scheduling and management. Over five months, Lintu implemented features such as a Plugin Plaza ecosystem, CSES data workflows, and dynamic theming, while refactoring the UI with PyQt5 and Qt for cross-platform consistency. Their approach emphasized modularity, stability, and extensibility, introducing a plugin system, CI/CD automation, and comprehensive error handling. Using Python, C++, and YAML, Lintu addressed complex integration challenges, improved user experience, and resolved critical bugs across Linux, Windows, and macOS. The work demonstrated depth in backend, UI, and system architecture.

February 2025 — Class-Widgets/Class-Widgets: Delivered core CSES workflow enhancements, UI/UX improvements, and stability fixes that collectively increase data portability, user satisfaction, and cross‑platform reliability. Key features delivered include CSES GUI integration with UI overhaul and import/export support; CSES data export for courses and subjects; and notable UI scheduling improvements and plugin ecosystem enhancements. Major bugs fixed across macOS and Linux improved startup reliability and prevented crashes (e.g., delete-without-selection, theme switch crash, version detection) while preserving existing behaviors. The work also includes documentation updates and code quality improvements that reduce tech debt and set the stage for future refactors. Overall impact: streamlined CSES data workflows, more robust cross‑platform operation, and a stronger foundation for a plugin-driven experience. Technologies/skills demonstrated: Qt/QML-based UI, C/C++ refactors, plugin architecture, configuration and scheduling workflow, and cross‑platform debugging.

October 2024 highlights for Class-Widgets/Class-Widgets focused on reliability, UX, and data integrity. Delivered fullscreen detection improvements with robust handling of dragged floating widgets and default time parts, advanced dynamic theming with hot updates and UI refinements, and corrected timeline data handling to ensure parts are returned only when corresponding data exists. Fixed theming when notifications are disabled and resolved multiple edge cases in timeline data checks. These efforts reduce edge-case failures, improve user experience, and reinforce data coherence across the widget, timeline, and theming systems.
