We have added an option to arrange products in 2 columns for mobile devices, which will increase the purchase convenience due to the fact that customers will see more products simultaneously. Moreover, if it is required to make the product image larger, you can arrange products in 1 column. 

To display products in 2 columns, you need to go to the mobile version editor, open the settings of the required element, and change the “Max items in row” from 1 to 2. 

Furthermore, you can change the gap between products (15 or 30 pixels).
