1. Currently, we don’t have such feature in our theme. But thank you for the suggestion, we will consider implementing this option in our future updates.
2. How exactly do you want to hide them? Do you want to make an empty space instead of these columns? Could you please provide a screenshot?
Another question, How can I reduce the size of the “Add to Cart”, “Quick View” and “Wishlist” icons on the shop list page for mobile devices only? (see attachment)
