What is the primary feature of Shopify's Online Store 2.0?

The primary feature of Shopify's Online Store 2.0 is the enhancement of the platform to support sections on every page along with improved app integration. This allows merchants to create more dynamic and flexible layouts throughout their store, rather than being limited to a standard homepage configuration.

By enabling sections on all pages, Shopify provides merchants with the ability to customize not just the homepage but product pages, collection pages, and other areas as well. This greater flexibility leads to a more engaging shopping experience as store owners can easily rearrange, remove, or add sections to align with their branding and marketing strategies.

Moreover, the improved app integration means that third-party apps can interact more seamlessly with the features of Online Store 2.0, expanding functionality without requiring significant custom coding or creating conflicts with existing theme elements. This integration capability encourages a more cohesive and streamlined approach to managing an online store, optimizing both performance and user experience.

In contrast, the other options suggest limitations or outdated features that do not reflect the advancements that have been made in Shopify's Online Store 2.0. Basic theme architecture and traditional coding methods do not capitalize on the modern capabilities that empower merchants to have more control and creativity in designing their online presence, while limited access to customization options
