Contributed two feature-level improvements to the ickshonpe/bevy repository, focusing on UI efficiency and accessibility within the Bevy Engine using Rust and ECS architecture. Developed an observer-based text synchronization system for multiple text inputs, which updates outputs only on TextEditChange events, thereby reducing unnecessary per-frame processing and lowering CPU usage. Additionally, implemented accessible tab navigation that excludes hidden UI elements by leveraging InheritedVisibility, ensuring keyboard focus cycles only through visible components. Both features reflect a thoughtful application of event-driven architecture principles, resulting in enhanced UI responsiveness and improved accessibility without introducing new bugs during the development period.
