In March 2026, Juan Garza enhanced the AvaloniaUI/avalonia-docs repository by delivering two front-end features focused on UI theming and user experience. He implemented a color mode toggle using React and TypeScript, allowing users to seamlessly switch between light and dark themes with intuitive moon and sun icons. Additionally, he led a comprehensive dark theme visual refresh, refactoring SCSS and CSS to unify color schemes, improve readability, and ensure consistent styling across components, dropdowns, and sidebars. These updates addressed maintainability and usability, reducing UI-related support needs and supporting smoother dark mode adoption for documentation users.
