Let your Top Menu Links be SEO friendly
As it is possible to set SEO Keyword per category on a Data tab, this Keyword can be used as a link to any category page on the top menu.
Having this mod in your /vqmod/xml/ folder will let you have the top menu links SEO friendly instead of the following for example: index.php?route=product/category&path=57

Example of SEO link in top menu http://localhost/opencart_v1.5.4.1/mp3-players
where:
localhost/opencart_v1.5.4.1 is the path to your opencart installation,
mp3-players is the Keyword input value saved per Category Data tab
