Adding the product features in the category list is a great tool to increase sales and show the customer the current product features. You only need to edit the product-list.tpl of your template, and put this code where you want (close to description tag in this example)
find:
<p class="product-desc" itemprop="description">{$product.description_short|strip_tags:'UTF-8'|truncate:360:'...'}</p>
and put:
<div class="pfeatures">{foreach from=$product.features item=feature}<div>{$feature.name}: <span>{$feature.value}</span></div>{/foreach}</div>
And you get the features in product list like in the example:
You can add styles to the features adding a class .pfeatures to the custom.css of the template:
.features{text-align:left; font-weight:bolder}
