Product descriptions on my site were lengthy due to redundant details for each product. So I purchased the Extra Tabs Extension and problem solved!
The only issue I had was that the extra tabs I created were placed at the end of all the baked in tabs such as Description, Reviews, Tags, etc. I needed my extra tabs to be right next to the Description tab.
To solve this, I made one simple change to /storefront/view/*mytemplate*/template/pages/product/product.tpl.
I moved <?php echo $this->getHookVar('product_features_tab'); ?> up between $tab_description and $review_status - see attachments.
Works perfectly!
