shadcn added freehand drawing to Copper, formalizing a workaround people already improvised.

Cmd + Right Shift + Shift opens a drawing editor from anywhere, with shapes, text, and colors (post). The replies explain why it landed: developers describing how they draw a table layout in Excalidraw rather than trying to explain it to Claude Code.

Small feature, correct observation about where prompting breaks down.
