Contributed to the OpenList-Frontend repository by delivering two core features aimed at improving batch operations and archive navigation. Developed Batch Rename Improvements, which introduced placeholder-based padding for sequential renaming, enhanced regex validation, and responsive UI feedback to minimize manual errors and streamline large-scale edits. Implemented Archive Preview, enabling users to preview files within archives and navigate inner paths without extraction, thereby improving content discovery and workflow efficiency. Leveraged React and TypeScript for robust front end development, incorporating JSON for data handling and internationalization support. The work focused on stability, validation, and scalability for handling larger datasets in complex environments.
