Sep 1, 2025September 2025 performance summary for cultuurnet/udb3-frontend: Delivered a front-end overhaul centered on labels management, introducing a reusable Table system and improved data presentation, translations, and navigation. Implemented a new /manage/labels page with search, pagination, and a dedicated UI sidebar link, and integrated the Table component across the Labels overview. Refined label query options (prefetch, suggestions-only, etc.), added translations for label strings, and stabilized SSR rendering with useEffect-based hydration fixes and exports. Introduced a feature-flag controlled UI flow for the sidebar and preserved default pagination behavior. Enhanced code quality with Prettier formatting, linting, and removal of unused variables, and centralized label values for consistency. Added Storybook entry for the Table component and aligned create/edit logic for maintainability.
