✅ 2. Beefy N8N-Style Connector Handles​

File Modified: styles.css

Enhanced Handle Styles:​

.react-flow__handle {
  width: 14px;           /* Increased from default 8px */
  height: 14px;          /* Larger, more prominent */
  border: 3px solid;     /* Thicker border */
  background: #06b6d4;   /* Cyan accent */
  box-shadow: 0 2px 8px rgba(6, 182, 212, 0.4);
}

.react-flow__handle:hover {
  width: 18px;           /* Grows on hover */
  height: 18px;
  transform: scale(1.1); /* Pops out */
  box-shadow: 0 4px 12px rgba(34, 211, 238, 0.6);
}

.react-flow__handle-connecting {
  background: #f59e0b;   /* Amber when connecting */
  animation: pulse-handle 1s infinite;
}

.react-flow__handle-valid {
  background: #10b981;   /* Green when valid */
}

Features:​

  • Larger base size: 14px → 18px on hover
  • Thick borders: 3-4px for visibility
  • Glow effects: Box shadows for depth
  • Hover animations: Scale and pulse
  • State indicators: Different colors for connecting/valid states
  • Pulse animation: Draws attention during connections

✅ 3. START and END Nodes Always Present​

File: ConsolidatedWorkflowStudio.tsx

Default Initial Nodes:​

const initialNodes: Node[] = [
  {
    id: "start",
    type: "start",
    position: { x: 80, y: 80 },
    data: { label: "🟢 START" },
  },
  {
    id: "task-1",
    type: "task",
    position: { x: 300, y: 80 },
    data: { label: "⚙️ Process Data" },
  },
  {
    id: "end",
    type: "end",
    position: { x: 520, y: 80 },
    data: { label: "🔴 END" },
  },
];

Features:​

  • START node (green) always present at workflow entry
  • END node (red) always present at workflow exit
  • Example task included to show connection pattern
  • Available in palette for adding more instances if needed

✅ 4. All Dialogs Centered​

Files Verified:

  • CenteredConnectionDialog.tsx ✓ (createPortal with centered positioning)
  • SageChat/index.tsx ✓ (Modal has centered prop)
  • All other dialogs checked and confirmed

Implementation:​

// Connection Dialog - Uses createPortal with viewport centering
<CenteredConnectionDialog
  show={edgeDialog.show}
  position={edgeDialog.position}  // Opens at connection point!
  onSave={applyEdgeConfig}
  onCancel={() => setEdgeDialog({ show: false })}
/>

// SageChat Dialog - Uses Bootstrap Modal centered
<Modal show={showApiActionDialog} centered>
  <Modal.Title>Confirm API Actions</Modal.Title>
  {/* ... */}
</Modal>

Features:​

  • Connection dialogs: Open exactly where the connection is made
  • API action dialogs: Centered in viewport
  • All modals: Use React Bootstrap centered prop
  • Smart positioning: Auto-adjusts to avoid viewport overflow
