Developed a robust drag-and-drop plugin extension for the jarun/nnn repository, focusing on enhancing download workflows and user experience. Leveraging Shell scripting and command-line tools, the work introduced improved error reporting, user-facing notifications, and a show-error flag for curl-based downloads to provide clearer visibility into failures. The implementation included optional system notifications on successful downloads and refined error capture for more informative user messages. Additionally, the developer addressed CI/CD reliability by adopting direct curl commands and CI-friendly error checks, resulting in more stable builds and reliable test outcomes. These changes streamlined file management tasks and reduced user friction throughout.
