April 2025 (2025-04) monthly summary for silx (silx-kit/silx). The month focused on delivering user-facing HDF5 UI improvements, expanding the Overlay Widgets framework, and strengthening documentation and testing practices. Key outcomes include pixel-based scrolling in Hdf5TableView and a programmatic selection API for HDF5 dialogs, a robust Hdf5TreeView.findHdf5Object that gracefully returns None for missing objects, and a refactored Overlay Widgets framework with new components (ButtonOverlay, LabelOverlay, WaitingOverlay) plus an OverlayMixIn to enable richer UI overlays. Documentation infrastructure for overlays was established via Read the Docs/Sphinx with updated PyQt5 requirements and examples. Supporting work included cleanup of an outdated Qt test skip and enhancements to test utilities to improve reliability. These results improve data navigation, UI richness, developer ergonomics, and overall product quality.
