I noticed there was a read and display of the Order Notes in the ShippingAddressStatic.ascx. I was able to reference the code in shoppingcart.aspx(.cs) and ShippingAddressEdit.ascx(.cs) to convert that display into and editable box. So now there is an Order Notes box permanently displayed on the one page checkout via the ShippingAddressStatic.ascx. Although the location is not ideal (on top of the shipping selection box), having it on the page is better than making the customer click to edit their address, or go back to the shopping cart.
Ideal location would be to have it in the right column.
