To get to the list of Products in the same Category as the Product in the Attributes Controller, you would either have to hit the EDIT PRODUCT and CANCEL or you could copy the button from the Products Price Manager and add it to the Attributes Controller something like:
<td class="smallText" align="center"><?php echo '<a href="' . zen_href_link(FILENAME_CATEGORIES, 'action=new_product' . '&cPath=' . $current_category_id . '&pID=' . $products_filter . '&product_type=' . zen_get_products_type($products_filter)) . '">' . zen_image_button('button_edit_product.gif', IMAGE_EDIT_PRODUCT) . '<br />' . TEXT_PRODUCT_EDIT . '</a>'; ?><br />
<?php echo '<a href="' . zen_href_link(FILENAME_CATEGORIES, 'cPath=' . $current_category_id . '&pID=' . $products_filter . '&product_type=' . zen_get_products_type($products_filter)) . '">' . zen_image_button('button_details.gif', IMAGE_DETAILS) . '<br />' . TEXT_PRODUCT_DETAILS . '</a>' . ' '; ?>
