Complete UX Journey Persistence

🎯 Philosophy

"Each component has to update our user-journey so that we know even that tab to keep selected."

Every piece of UI state should persist to create a truly seamless experience. Users should never have to:

• Re-select tabs
• Re-expand sections
• Re-configure views
• Re-position anything

The UI should remember EVERYTHING.

📊 What Persists Now

Complete Workspace State

interface WorkspaceState {
  // Core widget data
  widgetName: string;
  widgetType: CoreWidgetType;
  widgetDescription: string;
  propertyGroups: PropertyGroup[];
  variants: Array<{...}>;
  
  // UI State
  activePanel: 'design' | 'properties' | 'variants' | 'code' | 'preview';  // ✅ Active tab
  
  // UX Journey tracking
  expandedPropertyGroups: string[];  // ✅ Which groups are expanded
  selectedVariantId: string | null;  // ✅ Which variant is selected
  codeViewMode: 'component' | 'template' | 'styles' | 'all';  // ✅ Code view preference
  previewBreakpoint: 'base' | 'sm' | 'md' | 'lg' | 'xl' | '2xl';  // ✅ Preview size
  scrollPositions: {  // ✅ Scroll positions per panel
    properties?: number;
    variants?: number;
    code?: number;
  };
  
  lastSaved: number;
}

🎨 Features Implemented

1. Active Panel/Tab Persistence ✅

What Persists: The currently selected tab (Design, Properties, Variants, Code, Preview)

User Journey:

1. User clicks "Properties" tab
2. Adds property groups
3. Switches to "Design" tab
4. Closes browser
5. Returns → Still on "Design" tab! ✅

Implementation:

readonly activePanel = signal<'design' | 'properties' | 'variants' | 'code' | 'preview'>('design');

// Tracked in effect
const panel = this.activePanel();
state.activePanel = panel;

// Restored on init
this.activePanel.set(saved.activePanel);

2. Expanded Property Groups ✅

What Persists: Which property groups are expanded/collapsed

User Journey:

1. User expands "Layout" group
2. Collapses "Style" group
3. Switches tabs
4. Returns → Layout still expanded, Style still collapsed! ✅

Implementation:

readonly expandedPropertyGroups = signal<string[]>([]);

togglePropertyGroupExpanded(groupId: string) {
  this.expandedPropertyGroups.update(expanded => {
    if (expanded.includes(groupId)) {
      return expanded.filter(id => id !== groupId);
    } else {
      return [...expanded, groupId];
    }
  });
}

isPropertyGroupExpanded(groupId: string): boolean {
  return this.expandedPropertyGroups().includes(groupId);
}

3. Selected Variant ✅

What Persists: Which variant is currently selected/being edited

User Journey:

1. User creates 3 variants
2. Selects "Dark Mode" variant
3. Switches to Code tab
4. Returns → Dark Mode still selected! ✅

Implementation:

readonly selectedVariantId = signal<string | null>(null);

selectVariant(variantId: string) {
  this.selectedVariantId.set(variantId);
  this.logger.debug('Variant selected', { variantId });
}

4. Code View Mode ✅

What Persists: Which code view is selected (Component, Template, Styles, All)

User Journey:

1. User switches to "Template" only view
2. Works on template
3. Switches to Preview tab
4. Returns to Code → Still showing Template view! ✅

Implementation:

readonly codeViewMode = signal<'component' | 'template' | 'styles' | 'all'>('all');

setCodeViewMode(mode: 'component' | 'template' | 'styles' | 'all') {
  this.codeViewMode.set(mode);
  this.logger.debug('Code view mode changed', { mode });
}

5. Preview Breakpoint ✅

What Persists: Which breakpoint is selected in preview (Mobile, Tablet, Desktop, etc.)

User Journey:

1. User switches preview to "Mobile" (sm)
2. Tests responsive design
3. Switches to Properties tab
4. Returns to Preview → Still in Mobile view! ✅

Implementation:

readonly previewBreakpoint = signal<'base' | 'sm' | 'md' | 'lg' | 'xl' | '2xl'>('base');

setPreviewBreakpoint(breakpoint: 'base' | 'sm' | 'md' | 'lg' | 'xl' | '2xl') {
  this.previewBreakpoint.set(breakpoint);
  this.logger.debug('Preview breakpoint changed', { breakpoint });
}

6. Scroll Positions ✅

What Persists: Scroll position in each panel (Properties, Variants, Code)

User Journey:

1. User scrolls down in Properties panel
2. Switches to Variants tab
3. Returns to Properties → Scroll position restored! ✅

Implementation:

readonly scrollPositions = signal<{
  properties?: number;
  variants?: number;
  code?: number;
}>({});

updateScrollPosition(panel: 'properties' | 'variants' | 'code', position: number) {
  this.scrollPositions.update(positions => ({
    ...positions,
    [panel]: position
  }));
}

🔄 Auto-Save Flow

Effect Tracking

constructor() {
  effect(() => {
    // Track ALL signals
    const name = this.widgetName();
    const type = this.widgetType();
    const description = this.widgetDescription();
    const groups = this.propertyGroups();
    const variants = this.variants();
    const panel = this.activePanel();  // ✅ Tab
    const expandedGroups = this.expandedPropertyGroups();  // ✅ Expanded groups
    const selectedVariant = this.selectedVariantId();  // ✅ Selected variant
    const codeView = this.codeViewMode();  // ✅ Code view
    const previewBp = this.previewBreakpoint();  // ✅ Preview breakpoint
    const scrollPos = this.scrollPositions();  // ✅ Scroll positions

    // Build complete state
    const state: WorkspaceState = { ...all values... };

    // Auto-save
    this.storage.put(this.WORKSPACE_STATE_KEY, state);
  });
}

What Triggers Auto-Save

✅ Change widget type
✅ Add/remove property group
✅ Expand/collapse property group
✅ Switch tabs
