Create interactive tutorial that guides users through:

  1. "Click here to add your first block"
  2. "Drag it to the canvas"
  3. "Double-click to configure it"
  4. "Connect blocks by clicking ports"
  5. "Click Run to execute your flow"

Features:

UX1.2: Example Flows Library

Component: Add "Examples" button to header

Features:

Phase UX2: Enhanced Block Discovery

UX2.1: Block Search & Filter

File: Enhance block-library.component.ts

// Search bar at top of block library
<input 
  type="text" 
  [(ngModel)]="searchQuery" 
  (input)="filterBlocks()"
  placeholder="Search blocks... (e.g., 'add numbers')"
/>

// Smart filtering
filterBlocks() {
  // Search by:
  // - Block name
  // - Category
  // - Description
  // - Use case (semantic search)
  // - Tags
}

// Recent & Favorites
<div class="block-quick-access">
  <h4>Recently Used</h4>
  // Show last 5 used blocks
  
  <h4>Favorites</h4>
  // Show starred blocks
</div>

UX2.2: Block Preview

Enhancement: Hover preview before adding

// On hover over block in library
<div class="block-preview-tooltip">
  <h4>{{ block.name }}</h4>
  <p>{{ block.description }}</p>
  
  <div class="preview-example">
    <strong>Example:</strong>
    <code>{{ block.exampleUsage }}</code>
  </div>
  
  <div class="preview-inputs">
    <strong>Inputs:</strong> {{ block.inputs.map(i => i.name).join(', ') }}
  </div>
  
  <div class="preview-outputs">
    <strong>Outputs:</strong> {{ block.outputs.map(o => o.name).join(', ') }}
  </div>
</div>

Phase UX3: Enhanced Flow Editing

UX3.1: Keyboard Shortcuts

File: Add to logic-builder.component.ts

@HostListener('window:keydown', ['$event'])
handleKeyboardShortcut(event: KeyboardEvent) {
  // Ctrl+S / Cmd+S: Save flow
  if ((event.ctrlKey || event.metaKey) && event.key === 's') {
    event.preventDefault();
    this.saveCurrentFlow();
  }
  
  // Ctrl+Z / Cmd+Z: Undo
  if ((event.ctrlKey || event.metaKey) && event.key === 'z') {
    event.preventDefault();
    this.undo();
  }
  
  // Ctrl+Shift+Z / Cmd+Shift+Z: Redo
  if ((event.ctrlKey || event.metaKey) && event.shiftKey && event.key === 'z') {
    event.preventDefault();
    this.redo();
  }
  
  // Delete: Delete selected blocks
  if (event.key === 'Delete' || event.key === 'Backspace') {
    this.deleteSelectedBlocks();
  }
  
  // Ctrl+D / Cmd+D: Duplicate selected block
  if ((event.ctrlKey || event.metaKey) && event.key === 'd') {
    event.preventDefault();

  // Ctrl+A / Cmd+A: Select all blocks
  if ((event.ctrlKey || event.metaKey) && event.key === 'a') {
    event.preventDefault();
    this.selectAllBlocks();
  }
  
  // Escape: Clear selection / Close modals
  if (event.key === 'Escape') {
    this.clearSelection();
    this.closeAllModals();
  }
}

UX3.2: Context Menu (Right-Click)

@HostListener('contextmenu', ['$event'])
showContextMenu(event: MouseEvent) {
  event.preventDefault();
  
  const menu = [
    { label: 'Configure Block', icon: 'fa-cog', action: () => this.openBlockEditor() },
    { label: 'Duplicate', icon: 'fa-copy', action: () => this.duplicateBlock() },
    { label: 'Delete', icon: 'fa-trash', action: () => this.deleteBlock(), danger: true },

    { label: 'Add to Favorites', icon: 'fa-star', action: () => this.addToFavorites() }
  ];
  
  this.showContextMenuAtPosition(event.clientX, event.clientY, menu);
}

UX3.3: Undo/Redo System

Enhancement: Comprehensive undo/redo

// Already partially implemented in singularityService
// Enhance to support:
- Block addition/deletion

- Bulk operations

// Visual indicator
<div class="undo-redo-controls">
  <button 
    (click)="undo()" 
    [disabled]="!canUndo()"
    title="Undo (Ctrl+Z)">
    <i class="fas fa-undo"></i>
  </button>
  <button 
    (click)="redo()" 
    [disabled]="!canRedo()"
    title="Redo (Ctrl+Shift+Z)">
    <i class="fas fa-redo"></i>
  </button>
</div>

Phase UX4: Enhanced Error Handling & Validation

UX4.1: Pre-Execution Validation

File: libs/singularity-lib/src/lib/services/flow-validator.service.ts

@Injectable({ providedIn: 'root' })
export class FlowValidatorService {
  validateFlow(flow: LogicFlow): ValidationResult {
    const errors: ValidationError[] = [];
    const warnings: ValidationWarning[] = [];
    
    // Check for disconnected blocks
    const disconnected = this.findDisconnectedBlocks(flow);
    if (disconnected.length > 0) {
      warnings.push({
        type: 'disconnected_blocks',
        message: `${disconnected.length} blocks are not connected`,
        blocks: disconnected,
        suggestion: 'Connect these blocks or remove them'
      });
    }
    
    // Check for missing required inputs
    flow.blocks.forEach(block => {
      const missingInputs = this.findMissingInputs(block, flow);
      if (missingInputs.length > 0) {
        errors.push({
          type: 'missing_inputs',
          message: `Block "${block.name}" is missing required inputs`,
          blockId: block.id,
          missingInputs,
          suggestion: 'Configure these inputs or connect to other blocks'
        });
      }
    });
    
    // Check for undefined variables
    const undefinedVars = this.findUndefinedVariables(flow);
    if (undefinedVars.length > 0) {
      errors.push({
        type: 'undefined_variables',
        message: `Flow references undefined variables`,
        variables: undefinedVars,
        suggestion: 'Define these variables or use the Flow Tester to provide them'
      });
    }
    
    // Check for circular dependencies
    const circular = this.detectCircularDependencies(flow);
    if (circular) {
      errors.push({
        type: 'circular_dependency',
        message: 'Flow contains circular dependencies',
        cycle: circular,
        suggestion: 'Remove connections that create loops'
      });
    }
    
    return {
      valid: errors.length === 0,
      errors,
      warnings
    };
  }
}

UX4.2: Inline Validation Indicators

<!-- Show validation status on blocks -->
<div class="logic-block" [class.has-errors]="block.validationErrors.length > 0">
  <!-- Validation badge -->
  @if (block.validationErrors.length > 0) {
    <div class="validation-badge error" title="{{ block.validationErrors[0].message }}">
      <i class="fas fa-exclamation-circle"></i>
      {{ block.validationErrors.length }}
    </div>
  }
  
  @if (block.validationWarnings.length > 0) {
    <div class="validation-badge warning" title="{{ block.validationWarnings[0].message }}">
      <i class="fas fa-exclamation-triangle"></i>
      {{ block.validationWarnings.length }}
    </div>
  }
</div>

<!-- Validation panel -->
<div class="validation-panel" *ngIf="flowValidation()">
  <h3>Flow Validation</h3>
  
  @if (flowValidation().errors.length > 0) {
    <div class="validation-errors">
      <h4>Errors ({{ flowValidation().errors.length }})</h4>
      @for (error of flowValidation().errors; track error.type) {
        <div class="validation-item error">
          <i class="fas fa-times-circle"></i>
          <div>
            <strong>{{ error.message }}</strong>
            <p class="suggestion">💡 {{ error.suggestion }}</p>
          </div>
        </div>
      }
    </div>
  }
  
  @if (flowValidation().warnings.length > 0) {
    <div class="validation-warnings">
      <h4>Warnings ({{ flowValidation().warnings.length }})</h4>
      @for (warning of flowValidation().warnings; track warning.type) {
        <div class="validation-item warning">
          <i class="fas fa-exclamation-triangle"></i>
          <div>
            <strong>{{ warning.message }}</strong>
            <p class="suggestion">💡 {{ warning.suggestion }}</p>
          </div>
        </div>
      }
    </div>
  }
</div>

Phase UX5: Performance Optimizations

UX5.1: Virtual Scrolling for Large Flows

Enhancement: Only render visible blocks

// For flows with 100+ blocks
// Use virtual scrolling to render only visible blocks

@ViewChild(CdkVirtualScrollViewport) viewport!: CdkVirtualScrollViewport;

// Calculate visible blocks based on viewport
getVisibleBlocks(): LogicBlock[] {
  const viewportBounds = this.getViewportBounds();
  return this.canvasBlocks().filter(block => 
    this.isBlockInViewport(block, viewportBounds)
  );
}

UX5.2: Debounced Auto-Save

// Current: Saves on every change (can be expensive)
// Enhanced: Debounce saves to every 2 seconds

private saveDebouncer$ = new Subject<void>();

constructor() {
  // Auto-save every 2 seconds of inactivity
  this.saveDebouncer$.pipe(
    debounceTime(2000),
    distinctUntilChanged()
  ).subscribe(() => {
    this.saveCurrentFlow();
  });
}

// Trigger save
triggerAutoSave() {
  this.saveDebouncer$.next();
}

UX5.3: Lazy Load Block Library

// Don't load all 100+ block templates at once
// Load on-demand by category

async loadBlockCategory(category: string) {
  if (!this.loadedCategories.has(category)) {
    const templates = await import(`./templates/${category}-blocks`);
    this.blockTemplates.update(current => [...current, ...templates]);
    this.loadedCategories.add(category);
  }
}
