I've encountered a couple of times a use case for a horizontal cardlist, as compared to the current vertical cardlist. 

a horizontal cardlist is often used in: 

• dashboards
• e-shops
• portals
• phonebook

The idea of the horizontal cardlist is that it grows horizontally until the end of the page and than create a new row for all items. Often limited by an X amount per page for performance.

The current navigation option(clicking twice) is not very ideal, but allows for flexibility to open the detail or for example a next level of categories. 

I was wondering if anyone already encountered this need as well.
