4 Commits • 2 Features
Dec 1, 2025December 2025: Delivered two major feature efforts in mozilla/build-a-b: OWYW feature enhancements and Data War optimization. OWYW UI/flow improvements include tooltip clarity, correct triggering in the Data War phase, refined animation timing, and improved card reveal behavior, enabling faster and more intuitive user interactions. Data War optimization shortened animation duration by 100ms and addressed related accessibility considerations to improve responsiveness while preserving usability. This work reduces friction in core workflows, accelerates decision-making, and demonstrates a strong emphasis on maintainability and code quality.
