During June 2026, contributed to the adobe/da-live repository by enhancing the Rich Text Editor with superscript and subscript formatting options in the selection toolbar, enabling more advanced text styling for content authors. This work involved front end development using JavaScript and web components, with a focus on integrating new formatting features seamlessly into the existing editor interface. To ensure reliability, expanded unit test coverage for the ew-selection-toolbar and improved the test infrastructure by introducing minimal nx-picker and nx-popover fixtures. These efforts resulted in faster, more reliable authoring workflows and strengthened the overall robustness of the editor’s styling capabilities.
