During August 2025, Ellis Chae developed a comprehensive Drawing Tools Suite for the yorkie-js-sdk repository, introducing Pen, Fading Pen, Highlighter, and Eraser tools with enhanced stroke rendering. Leveraging JavaScript and the Canvas API, Ellis improved visual fidelity by integrating RDP simplification and Catmull–Rom interpolation, resulting in smoother, more consistent drawing experiences. A versatile color picker supporting multiple modes was added and integrated across all tools, ensuring cohesive UI/UX design. The work focused on real-time collaboration scenarios, maintaining stability while expanding functionality. These contributions laid a robust foundation for future tool extensions and improved designer workflows within the SDK.
