How do I create a new layout for a data entry screen?

Click on the little drop down arrow to the right of the current layout name and find the Copy option and change the name of the current layout to any one you wish and press enter on your keyboard. You can now set this up however you wish and it will be saved with that name and be an option in the layout box. NB please note that if you have made changes to a layout and it is called PigVision, please use the above to create a new name as otherwise the original layout will be overwritten when a program update is installed.
