Mar 1, 2026March 2026 focused on expanding test coverage for the JupyterLab file browser, delivering automated tests for single-click navigation. The work validated enabling/disabling single-click navigation, preserved double-click behavior, and exercised checkbox interactions to ensure consistent user experience. The implementation references JupyterLab repo jupyterlab/jupyterlab with commit 681860de6d98aa68e2e774af56dd91938820c1f3 (Add tests for single-click navigation in filebrowser). This improvement reduces regression risk, strengthens CI reliability, and accelerates feature iteration by catching edge cases early.

Jul 1, 2025July 2025: Implemented data- attribute normalization for the ToolbarButtonComponent to ensure consistent and HTML5-compliant dataset handling across JupyterLab toolbars. Fixed incorrect handling of custom data attributes by introducing a normalization function that prefixes all dataset attributes with 'data-', improving robustness and UI stability.
