I've created a next-gen project, and wanted to add some fields in the main view.
I can add primary and secondary fields (appears in the upper and lower right pane), but fields that appear in the main view - between the left and the right pane - can't be added/changed.
How can fields be added here?
Can I in any way change my settings to go back to the old layout instead of next-gen?
TIA
Peter
