Sep 1, 2025September 2025: Delivered targeted UI and workflow improvements for label-studio that improve annotation throughput and accuracy. Implemented Outliner: Media Start Time Sorting to order regions by audio/video start times, with UI and logic that only displays when media time information is present and that respects the labeling configuration. Fixed Annotator Performance workspace dropdown visibility for long workspace names by adding a truncate styling to the label, eliminating overflow issues. These changes reduce manual reordering, improve consistency with labeling config, and demonstrate frontend expertise in UI components, state management, and cross-component coordination.
