April 2026 monthly summary for paranext-core focusing on delivering a renderer-side Overlay UI Management Service and its impact on UX, accessibility, and extension capabilities. What was delivered: - Overlay UI Management Service for context menus, modal dialogs, and popovers in sandboxed WebView iframes. Implemented as a renderer-only service that renders overlays in the top-level document and handles cross-context coordination, translation, validation, debounce, focus save/restore, aria-live announcements, auto-dismiss on scroll/blur/tab-change, and localization support. Commit reference: 6d35c77053f401a832f983b3331f2bcf76cddf33. Why it matters: - Enables extensions and UI components in sandboxed iframes to request and render overlays reliably in the main document, improving consistency and user experience. - Enhances accessibility and localization readiness for dynamic overlays, supporting better assistive tech narration and internationalization. - Reduces rendering complexity within iframes and improves performance by isolating overlay rendering to the top-level document. Impact: - Business value realized through more robust in-app UI interactions, smoother context menus and dialogs, and a foundation for future UI extension capabilities. - Technical achievements include cross-context coordinate handling, input focus management, and accessibility features that align with product UX goals.
