From business point of view, shopkeepers basically want their clients to:
- Find a product
- Add it to the cart
- Proceed to checkout
What I'm missing, is more attention to the "Add to cart" and "Checkout" -buttons. I feel some carts (Magento to name one) have succeed in this by using clear orange colored buttons to get attention. It would be great to have some pre-coded styles to choose from in Ubercart settings - to help client to focus to shopping, not just browsing.
