During February 2026, Henry Saniuk developed a customizable Button styles prop for the Khan/wonder-blocks repository, enabling precise control over startIcon and endIcon sizing and allowing overrides of default theme settings. He implemented this feature using React with JavaScript and TypeScript, ensuring compatibility with existing hover, active, and focus states while aligning with established ActivityButton patterns. The update addressed practical UI needs, such as supporting 24x24 icons for Khanmigo Concierge triggers, and included comprehensive usage examples. The work was merged after passing all required checks, reflecting a focused and well-integrated contribution to front end component flexibility and maintainability.
