I looked at the code of the import/export plugin, not the other one. The one I looked at already includes filters that will let you include extra data in the export and then to do something with it in the import, but there isn’t any documentation I can find on how to use it. With information on how to use it someone could probably create filters that let you transfer ACF fields for widgets. But this would likely mean you need to use the same plugin for both export and import. Is there a reason you’re using separate ones?
