Add Product Variants Index to Navigation Menu

[mgambella]

Description:

While working on product management, I discovered a hidden but incredibly useful feature that significantly improved my workflow: the Product Variants index page with bulk editing capabilities.

Current Behavior:

The default product management interface (/admin/commerce/products/products?source=productType%3A...) displays products with variants accessible only through a right-side panel. This makes bulk editing variants cumbersome and time-consuming, especially when working with multiple variants across different products.

Discovery:

By manually changing the URL from /admin/commerce/products/... to /admin/commerce/variants/..., I discovered a dedicated Product Variants index page that includes:

• A comprehensive list view of all variants
• Bulk edit capabilities
• Sortable columns
• Better data visibility

This view saved me hours of work, but I only found it by accident through URL manipulation.

Expected Behavior:

The Product Variants index should be easily discoverable and accessible through the main navigation. Specifically:

• Add a "Product Variants" menu item under Commerce → Products in the left sidebar navigation
• Alternatively, add a toggle/tab in the Products view to switch between "Products" and "Variants" view
• Make this feature visible in the documentation

Why This Matters:

For shops with products that have multiple variants (different sizes, colors, materials, etc.), being able to view and edit all variants in a unified index with bulk operations is essential for efficient product management. Having this feature hidden behind manual URL manipulation means most users will never discover this time-saving functionality.

Environment:

Craft Commerce version: 5.5.0
Craft CMS version: 5.8.20

Additional Context:

The feature already exists and works perfectly - it just needs to be surfaced in the UI for discoverability.
