You can customise the data displayed on most of the datagrids in the backoffice by editing your 'views', or by creating new global or personal views.
Open the left column on any grid by clicking the chevron, then click 'Edit' against any of your views, or click 'Create a new view':
There are many potential fields that can be added. Open up each section and check the options you want to show. Checked items will appear on the right of the page. Once added, you can change the order they will appear on the page by dragging them up or down. Click save when done, then Publish changes if you are editing or creating a new global view.
