Hello,
01. Breadcrumbs can improve navigation and user experience, especially for stores with many categories and subcategories. They help users easily go back to previous sections, reducing frustration. If your store has a simple structure, you can remove them, but for better customer retention, it’s usually recommended to keep them.
02. White space improves readability and enhances visual appeal. However, too much empty space can push important content (like product images and title) too far down, requiring unnecessary scrolling. A moderate amount of space is ideal—enough to maintain a clean layout while keeping key elements easily accessible.
Best Regards,
