first of all, great web application. OsCommerce made me hate eCommerce, but OpenCart gives me hope
.I've just started exploring it, but I noticed some usability issues related to the reviews page.
1) The "Reviews page" and "Product X Review" have no "Back to product" button, or usable breadcrumb (eg Home » Product 1 » Reviews);
2) On the "No product reviews" page, the "Continue" button should go back to the product, not the main page;
3) The "Write a review on this product!" box disappears on the "No product reviews" page;
4) On the Product page, it would be better to replace the "Reviews" button with a "No reviews yet" notification. Don't make the user click the button only to be sent to a useless page.
5) Why does the functionality change when viewing a review? A "Write review" button appears, and the "Write a review on this product" box diappears. Shouldn't this be consistent across all pages?
6) I think it's more intuitive if the button / link for writing reviews is in the content of the "current page" (eg. after the product information, images, etc.). The column on the left usually holds navigation links related to the entire store. The user doesn't know that information related to the current product might appear there.
7) It would be nice if the latest reviews could be displayed on the product page without having to access a separate page (eg. like in amazon.com). People want to read some customer opinions on-the-fly. If they want even more, then they should click the "Reviews" button. But when they can see reviews easily (and assuming your store sells products that people are pleased with), customers will be more likely to buy.
