Hide Carts from Add Order in backoffice

[televi]

In backoffice, when an employee creates an order i would like to hide the "Carts" tab and only show the Orders tab.

 

Or if its easier maybe make the Orders tab as the default tab instead of the Carts tab

 

(my attachment shows which part i am talking about)

 

I tried editing the myadmin/themes/default/template/controllers/orders/form.tpl but i cant figure it out
