GitHub Copilot app adds customizable bidirectional canvases via /create-canvas
The GitHub Copilot app introduces 'canvases' (canvas extensions): customizable, bidirectional UI tools—kanban boards, checklists, dashboards, forms, etc.—that the Copilot agent generates and updates from a plain-English description using the /create-canvas skill. Canvases are saved as extensions for reuse and can be shared with a project or kept personal, letting agent and user interact with the same live interface.
