During January 2026, Tsdrppy developed a manual coolant tank refill feature for the SymmetricDevs/Susy-Core repository, focusing on enhancing maintenance workflows for single-block generators. Leveraging Java and user interface design skills, Tsdrppy implemented container-based interactions on tank widgets, allowing users to refill coolant tanks using water buckets, drums, or cells. This addition improved operational flexibility and reduced the need for manual workarounds in field deployments. The work demonstrated a practical application of game development principles, addressing a specific usability gap and contributing to the maintainability and reliability of generator systems. The feature was delivered as a single, well-scoped enhancement.
