I've been using this mod for a few months now and love it. One thing I just now realized is that you can change the name of your products without breaking the links to your website. This is invaluable if you need to make modifications to your product name after you have an established ranking on search engines.
For example:
Let's say your current link using DSEFU is:
www.yoursite.com/Old-Product-Name-pr-123.html
And you change the product name to New Product Name. Your new DESFU will be:
www.yoursite.com/New-Product-Name-pr-123.html
However, even if you put the old url in your browser, it will take you to the product. This is because it finds the product based on the"-pr-123" part of the url (which is the product id). Therefore, you could put whatever you want in front of "-pr-123" and it will take you to that product.
So, great mod! One less thing to worry about when changing the product name. Thanks Hooter!
