Christy Or built a mobile UI configuration feature for the miraheze/mw-config repository, focusing on enhancing mobile usability for wiki namespaces. By introducing the wgMFNamespacesWithoutCollapsibleSections option in PHP, Christy enabled administrators to disable collapsible sections for specific namespaces such as File, Category, Special, and Media, addressing the deprecation of wgMFCollapseSectionsByDefault. This work leveraged configuration management and wiki administration skills to create a maintainable, namespace-level approach for UI behavior. Although no bugs were fixed during this period, the feature established a foundation for future UI customization, reflecting a targeted and maintainable solution to evolving platform requirements.
