It would be very desirable to have more flexibility to style and design product pages. For example, being able to add more dynamic blocks that apply to all products. If products have long descriptions, it would be useful to place content blocks underneath the product image instead of having all text displayed on only one side.
It would also be great to have more styling options for buttons, both within the store widget and on the product page itself. Ideally, this would apply to all pages related to the store experience.
