- Updated CanvasSidebar to accept canvasId as a prop, enabling dynamic content based on the current canvas. - Refactored CanvasToolbar to implement a dropdown menu for adding nodes, improving usability and organization. - Introduced new node types and updated existing ones in the node template picker for better categorization and searchability. - Enhanced AssetNode to utilize context for asset browser interactions, streamlining asset management on the canvas. - Improved overall layout and styling for better user experience across canvas components.
