In February 2026, Alex developed the overhead-mute plugin for audio channel management within the runelite/plugin-hub repository. Focusing on plugin development using plaintext configuration, Alex designed and implemented a modular solution that enables users to mute specific audio channels, addressing the need for reduced audio clutter during streaming and recording. The work involved end-to-end feature delivery, from initial design through integration and repository contribution, without major bug fixes required during the period. By expanding the plugin ecosystem and enhancing user control over audio settings, Alex demonstrated depth in plugin architecture and practical application of plaintext-driven configuration for user experience improvements.
