## ✅ What Was Accomplished

### 1. Loading States & UX Improvements ✅
**Modified**: `resources/views/websites/theme-library/index.blade.php`

**Enhancements**:

#### A. Toast Notification System
Created elegant, animated toast notifications to replace browser alerts:

```javascript
function showToast(type, message) {
    const toast = document.createElement('div');
    toast.className = `custom-toast toast-${type}`;
    toast.innerHTML = `
        <div class="toast-content">
            <i class="bi bi-${type === 'success' ? 'check-circle-fill' : 'exclamation-circle-fill'} me-2"></i>
            <span>${message}</span>
        </div>
    `;
    document.body.appendChild(toast);
    setTimeout(() => toast.classList.add('show'), 100);
    // Auto remove after 3 seconds
    setTimeout(() => {
        toast.classList.remove('show');
        setTimeout(() => toast.remove(), 300);
    }, 3000);
}
```

**Features**:
- Animated slide-in from right
- Auto-dismiss after 3 seconds
- Success (green) and error (red) variants
- Bootstrap Icons integration
- Smooth transitions

#### B. Loading Overlay System
Full-screen loading overlay for long operations:

```javascript
function showLoadingOverlay(message = 'Loading...') {
    const overlay = document.createElement('div');
    overlay.id = 'loadingOverlay';
    overlay.className = 'loading-overlay';
    overlay.innerHTML = `
        <div class="loading-content">
            <div class="spinner-border text-light mb-3" role="status">
                <span class="visually-hidden">Loading...</span>
            </div>
            <div class="text-light">${message}</div>
        </div>
    `;
    document.body.appendChild(overlay);
    setTimeout(() => overlay.classList.add('show'), 10);
}
```

**Features**:

---

### 2. Theme Export/Import Feature ✅
**New Feature**: Complete import/export functionality for theme customizations

#### A. Controller Methods Added
**File**: `app/Http/Controllers/ThemeLibraryController.php` (lines 218-332)

**exportCustomizations()** method:
```php
public function exportCustomizations(Website $website)
{
    $exportData = [
        'theme_slug' => $activeTheme->theme->slug,
        'theme_name' => $activeTheme->theme->name,
        'theme_version' => $activeTheme->theme->version,
        'exported_at' => now()->toIso8601String(),
        'website_name' => $website->name,
        'customizations' => [
            'colors' => $activeTheme->color_overrides ?? [],
            'fonts' => $activeTheme->font_overrides ?? [],
            'settings' => $activeTheme->settings_overrides ?? [],
            'header' => $activeTheme->header_settings ?? [],
            'footer' => $activeTheme->footer_settings ?? [],
        ],
        'components' => $activeTheme->components->map(...)->toArray(),
    ];

    $filename = 'theme-export-' . $website->slug . '-' . now()->format('Y-m-d-His') . '.json';

    return response()->json($exportData)
        ->header('Content-Type', 'application/json')
        ->header('Content-Disposition', 'attachment; filename="' . $filename . '"');
}
```

**What It Exports**:
- Theme identification (slug, name, version)
- Export metadata (timestamp, website name)
- All color customizations
- Font customizations
- Settings overrides
- Header & footer settings
- Component customizations

**importCustomizations()** method:
```php
public function importCustomizations(Request $request, Website $website)
{
    // Validate JSON file
    $request->validate([
        'import_file' => 'required|file|mimes:json|max:2048',
    ]);

    // Parse and validate import data
    $data = json_decode($contents, true);

    // Verify theme exists
    $theme = Theme::where('slug', $data['theme_slug'])->first();

    DB::transaction(function () use ($website, $theme, $data) {
        // Switch to theme if needed
        if (!$activeTheme || $activeTheme->theme_id !== $theme->id) {
            $activeTheme = $this->themeService->switchTheme(...);
        }

        // Apply all customizations
        $activeTheme->update([
            'color_overrides' => $data['customizations']['colors'] ?? [],
            'font_overrides' => $data['customizations']['fonts'] ?? [],
            'settings_overrides' => $data['customizations']['settings'] ?? [],
            'header_settings' => $data['customizations']['header'] ?? [],
            'footer_settings' => $data['customizations']['footer'] ?? [],
        ]);

        // Clear cache
        $this->themeService->clearThemeCache($website);
    });
}
```

**Safety Features**:
- File validation (JSON only, max 2MB)
- Format validation
- Theme existence check
- Transaction-based (all-or-nothing)
- Automatic cache clearing

#### B. Routes Added
**File**: `routes/web.php` (lines 758-759)

```php
Route::get('/themes/export', [ThemeLibraryController::class, 'exportCustomizations'])
    ->name('website.themes.export');
Route::post('/themes/import', [ThemeLibraryController::class, 'importCustomizations'])
    ->name('website.themes.import');
```

#### C. UI Implementation
**File**: `resources/views/websites/theme-library/index.blade.php` (lines 209-254)

**Export/Import Button**:
```html
<button class="btn btn-outline-success" data-bs-toggle="modal" data-bs-target="#exportImportModal">
    <i class="bi bi-box-arrow-up me-1"></i> Export/Import
</button>
```

**Modal with Two Sections**:

1. **Export Section**:
   - One-click download button
   - Generates timestamped JSON file
   - Includes all customizations

2. **Import Section**:
   - File upload form
   - JSON file validation
   - Warning message about replacement
   - Loading state during import
   - Success/error toast notifications

**JavaScript Handler** (lines 578-615):
```javascript
document.getElementById('importThemeForm')?.addEventListener('submit', function(e) {
    e.preventDefault();

    const formData = new FormData(this);
    const submitBtn = this.querySelector('button[type="submit"]');

    // Show loading state
    submitBtn.disabled = true;
    submitBtn.innerHTML = '<span class="spinner-border spinner-border-sm me-1"></span> Importing...';

    fetch(`/websites/${websiteId}/themes/import`, {
        method: 'POST',
        headers: { 'X-CSRF-TOKEN': csrfToken },
        body: formData
    })
    .then(response => response.json())
    .then(data => {
        if (data.success) {
            bootstrap.Modal.getInstance(document.getElementById('exportImportModal')).hide();
            showToast('success', data.message);
            setTimeout(() => window.location.reload(), 1500);
        } else {
            showToast('error', 'Error: ' + data.message);
        }
    });
});
```

### 3. Component Search/Filter ✅
**Status**: Already implemented and working

**File**: `resources/views/pages/custom-builder.blade.php` (lines 3145-3176)

**Features**:
- Real-time search as you type
- Searches component name and type
- Hides sections with no matching components
- Shows all when search is cleared
- Case-insensitive matching

```javascript
filterComponents(searchTerm) {
    const componentItems = document.querySelectorAll('.component-item');
    const sections = document.querySelectorAll('#components-panel .mb-4');

    if (!searchTerm) {
        // Show all
        componentItems.forEach(item => item.style.display = 'block');
        sections.forEach(section => section.style.display = 'block');
        return;
    }

    // Filter by search term
    sections.forEach(section => {
        let hasVisibleItems = false;
        const items = section.querySelectorAll('.component-item');

        items.forEach(item => {
            const text = item.textContent.toLowerCase();
            const type = item.dataset.type.toLowerCase();

            if (text.includes(searchTerm) || type.includes(searchTerm)) {
                item.style.display = 'block';
                hasVisibleItems = true;
            } else {
                item.style.display = 'none';
            }
        });

        // Hide section if no visible items
        section.style.display = hasVisibleItems ? 'block' : 'none';
    });
}
```

**Error Handling Pattern**:
```javascript
.then(response => response.json())
.then(data => {
    hideLoadingOverlay();
    if (data.success) {
        showToast('success', data.message);
        setTimeout(() => window.location.reload(), 1000);
    } else {
        showToast('error', 'Error: ' + data.message);
    }
})
.catch(error => {
    hideLoadingOverlay();
    showToast('error', 'An error occurred during operation');
    console.error('Error:', error);  // For debugging
});
```
