During January 2025, Ek Speeder contributed to the uBlockOrigin/uAssets repository by delivering targeted user experience improvements in web filtering. They developed a filter to block Trakt.tv ad wrappers by identifying elements with specific ID patterns linking to advertising, directly addressing user complaints and reducing ad clutter. Additionally, Ek enhanced the PlantUML editor layout by introducing custom CSS filter rules to streamline the sidebar and remove empty sections, improving usability. Their work demonstrated proficiency in ad blocking, filter list management, and CSS-driven DOM manipulation, with disciplined change-tracking and clear issue references, resulting in measurable improvements to high-visibility web surfaces.
