Hi,It is indeed a gutter-sized space being added after the last row of cards. I would like to address this in an upcoming release but can't provide an ETA yet.Best regards,Andrei

Thanks for the suggestion!As David said, additional design features will come to further expand on the design flexibility with layouts and cards. In-app search is also coming very very soon.The reason we didn't go the Custom Storefront route was the big impact it had on the app performance. Our commitment is to enable you to bring highly designed and highly performant apps to market.Best regards,Andrei
