The purpose of this modification is to basically make the life easier of those of you whom rely heavily on the comments box
to give your customer information about their order.
I got quite tired of typing or copying and pasting in the same text to let their customer know their order has been shipped, backordered, etc.
Comments Toolbar simply adds any number of buttons under your comments box in orders.php that basically act as macro buttons. You customize the buttons and text by editing the included html file.
