August 2025 focused on performance, accessibility, and reliability improvements for element-web. Key outcomes include performance gains from virtualizing the room list (react-virtuoso) and scroll-optimized rendering, significant UI/UX refinements in ListView and room list, clearer encryption status indicators, and stronger test stability. The changes reduce UI glitches in large workspaces, improve accessibility and keyboard usability, and increase release confidence through more robust tests. What was delivered: - Virtualized room list with react-virtuoso for smoother scrolling and accessibility improvements; prevented context menus from rendering while scrolling. - ListView navigation improvements: decoupled selection logic, fixed profile opening on item click, and disabled arrow-key navigation when modifier keys are active to avoid conflicts with global shortcuts. - Room list encryption UI indicator update: blue lock for unencrypted rooms and removal of grey shield for encrypted rooms; tests updated accordingly. - Layout stability enhancements: minimum width enforcement via constant and improved resizer logic to prevent layout collapse; unit tests added. - Dialog accessibility improvements: main dialog made focusable to improve keyboard navigation and Escape handling; tests and snapshots updated. - Test reliability improvements: added visibility checks before keyboard actions, refactored RoomHeader tests for reliability and isolation, and introduced mocks (e.g., CallStore.getCall) to stabilize test runs.
