"You can also use unpublished categories to add a modifiers to your products"
good tip !
But as you say - only 80%...
What if the special price is out dated ?
Than the products have still the "FEatured Product" checkbox ist still actvivated...but the priceis not "special"...
On the other hand I have to activate it because it will not be shown up in the featured products module...
VM has no link to "Products with calculation rule xyz...."....if there would be a link which shows only products with a special rule....than it would work...
