Worked on the th-ch/youtube-music repository to deliver full Spanish localization and targeted front end enhancements over a two-month period. Leveraged Weblate to translate and integrate over 400 UI strings, ensuring comprehensive i18n and localization coverage for Spanish-speaking users. Implemented these translations using JSON, adding them to the i18n directory to streamline future language support. Enhanced the user interface by introducing a navigation bar clock and options for converting Chinese characters, broadening accessibility and usability. Focus remained on internationalization and user experience improvements, with no major bug fixes, resulting in a more inclusive and adaptable application for diverse audiences.
