From the Product Listing tab:
Language & currency: applies to My Products in Branvas and to your store listings.
Listing content: whether/how your brand name appears in product titles, and the description writing style (Direct & Clear, Warm & Inviting, or Elevated).
SEO: whether to publish Branvas-generated meta titles and descriptions, include your brand name in the meta title, and add a call-to-action to the meta description.
Background color: ivory (default), pure white, or cool grey, applied to all products in My Products.
Retail prices are entirely yours, with no restrictions from Branvas. Change them from My Products or the product edit page. Remember to make all listing edits inside Branvas, not Shopify (see How do I connect my store and add products?).
