During January 2026, Seasmoffi focused on maintaining the MangaOkuTr extension within the keiyoushi/extensions-source repository by executing a domain migration from mangaokutr.com to mangaokutr.net. This work involved updating all relevant URLs and aligning the base URL to ensure the extension continued to function seamlessly for users after the domain change. Seasmoffi utilized Kotlin and Gradle as core technologies, applying Android development skills to implement the update efficiently in a single commit. The work addressed a critical bug, preventing broken links and preserving user trust, and demonstrated careful attention to detail in maintaining application reliability during infrastructure transitions.
