During April 2026, this developer enhanced the decolua/9router repository by building a feature that streamlines user configuration for DNS mapping within the MitmToolCard component. They introduced a centralized TOOL_HOSTS constant in JavaScript, enabling per-tool DNS entries to be mapped and displayed directly in the user interface. This approach, implemented using Node and React, reduces manual setup and improves the scalability of host management across tools. The work focused on end-to-end integration and quality, with no major bugs reported during the period. The feature lays a foundation for more flexible and maintainable front end configuration in future development.
