Webify Metafields Editor

Using this for related product metafields. What stops me giving this a higher mark is the search function which is a complete waste of time as it only works if you know the exact product title. If there was a way of searching product titles for specific keywords I'd give this 4 stars. And if there was a bulk edit function rather than having to click on every single product one by one, it'd get 5 stars.
