During March 2025, Glastonbridge enhanced accessibility and keyboard navigation across the microsoft/pxt-microbit and microsoft/pxt repositories. They focused on restructuring the DOM and refining tab order to make simulator elements fully keyboard-interactive, while also improving focus management and ARIA compliance throughout the PXT UI. Using TypeScript, CSS, and JavaScript, Glastonbridge implemented clear focus indicators and addressed navigation friction for assistive technology users. Their work spanned home screen carousels, editor selection, and sidebar toggles, aligning both repositories with WAI-ARIA standards. The depth of these changes improved usability for keyboard users and established a more accessible, consistent front-end experience.
