You can change the order that forms appear by going to Admin > Config > Core Setup > Forms.
Here you can see your existing forms order.
Click on a form you wish to re-position with the left side of your mouse, hold down the key and drag the form to where you wish it to be.
Once you release the mouse key, the form will have moved position.
The positioning here feeds through to the Manage Register area as well as other reporting areas and Comms.
