It would be great if we could change the order it scrapes and lists selectors.
In the event I need to add/remove a new field, I hate having to either rebuild, reimport, or edit the csv.
I think it will be certainly possible just as easy as drag-n-drop in near future.
I too would like this feature!
I have managed to work around by exporting the sitemap, editing in external JSON editor, re-importing. But this is tedious and error-prone.
