Key Patterns

Mode-Aware Components

export const VideoNode = memo(function VideoNode({ id, data, selected }: Props) {
  const canvasMode = useAppStore((state) => state.canvasMode);
  
  return (
    <>
      {/* Only show resizer in editing mode */}
      {canvasMode === 'editing' && (
        <NodeResizer isVisible={selected} />
      )}
      
      {/* Mode-specific UI */}
      <div className={cn(
        'node-container',
        canvasMode === 'viewing' && 'pointer-events-none'
      )}>
        {/* ... */}
      </div>
    </>
…

Presentation Order

// Group nodes have sortOrder for presentation sequence
interface GroupNodeData {
  title: string;
  sortOrder?: number;  // Lower = earlier in presentation
  description?: string; // Shown on hover in presenter sidebar
}

Script/Teleprompter

// Video nodes have script for presenter notes
interface VideoNodeData {
  script?: string;  // Markdown-formatted presenter notes
  // ...
}

Component Structure

components/presenter/
├── PresenterView.tsx       # Main presenter container
├── PresenterSidebar.tsx    # Navigation sidebar with groups/nodes
├── PresenterSlide.tsx      # Single node display

Implementation Notes

Auto-Advance

• Nodes can auto-advance after their content completes
• Videos: After playback ends
• Images: After configured duration
• Configurable per-node or globally

Script Visibility

• Scripts visible to presenter only
• Audience sees content without notes
• Font size controls for readability

Responsive Behavior

• Mobile: Simplified controls
• Tablet: Touch gestures
• Desktop: Full keyboard navigation

Rules

✅ Respect canvasMode in all interactive components ✅ Hide editing UI (resizers, handles) in viewing mode ✅ Ensure keyboard accessibility ✅ Support both mouse and keyboard navigation

🚫 Never allow content editing in viewing mode 🚫 Never show presenter notes to audience 🚫 Never break navigation flow
