@mynameisadamf what do you think about this UX improvement?

@blittle How are these breadcrumbs being populated? We did present the idea of adding breadcrumbs prior, following the OS solution, but was manual. If dynamically populated referencing the collection, what happens when the product is assigned to more than one collection?

@mynameisadamf They are just following the URL Home | collections | collection-handle. There is no nested collections. It's just a basic one-level breadcrumps navigation

But if a merchant can assign a product to many collections. Which collection-handle would display in the breadcrumb?

I'm just making sure we're demoing the right solution for a real-world scenario.
