April 2026 — The NeoShowcase project delivered meaningful performance, security, and maintainability improvements. Key features were implemented to improve user experience on large datasets, strengthen deployment reliability, and elevate code quality for faster future iterations. Major bugs related to UI rendering stability were addressed, and a broad set of refactors reduced technical debt without sacrificing velocity. Key features delivered: - UI List Rendering and Virtualization Improvements: Migrated from tanstack/virtual to virtua and integrated Virtualizer to optimize scroll handling and rendering efficiency for large lists. This reduces rendering latency and improves perceived performance during scrolling on dense datasets.
