Sorting products in category

It should be possible to sort products in the product list in a category - Just like I can position the categories.

The byer have a sorting option - the use of this should be possibel to unselect from admin. No it has to be removed from the template.

This because of the design - you may want to have the products lined up in your spesial way. You can do this by code number when you set it up - but if you later make a change or delete one code number and later put it back the sorting is out of order.
