If you got tired adding special price for new added products by going special price module, with this modification you can enter/edit special price durind new product add or editing existing product.

If special price is set to "0" it automatically disable its special state.

Ps. For now you cannot enter 5% discounts as special price, you can enter only amount. Adding this feature is not so hard but in 5 minute I did this. Maybe somebody does that....
