Collection Item Options – Item list columns

Hi

In the admin screen for a collection I am showing a category in the item list columns, as well as a product image thumbnail and product code. Clicking on them allows me to reorder the list - a very nice new feature, thanks.

However, clicking the category doesn't sort the items into categories – it adds a new item. Is this the expected behaviour or should I call Department UXB?

The generated link is https://DOMAIN/perch/core/apps/content/collections/?id=1&sort=product_cat

Many thanks in advance,

Jon
