With the Grids Editor, you can customize existing views, but also create new views, in all 3 interfaces: products, orders and customers.
First choose the grid you want to add the view onto, from the drop down menu at the top of the left handside column
Click on the
icon to create a new view
Give it a name and validate on OK
Select this new view in the list
The right handside column shows all fields available that you can add
To add a field to your new view, simply drag and drop it from the right handside to the central column. Note that you can select multiple fields before dragging/dropping them
Once all the fields you need are present, you can re-arrange the order by a drag/drop, and do not forget to validate the new order by clicking on this icon
on the toolbar
Once you're done, hit F5 (or CMD+R if on Mac)
You can now see your new view
