Import/Export preferences needs better documentation
Current documentation: https://docs.gimp.org/2.10/en/gimp-pimping.html#gimp-prefs-import-export
The import/export preferences don't have any documentation except saying "self-explanatory". We need to improve this and maybe also break the page up since it's pretty long.
One specific case that needs to be addressed is that Default export file type
is only relevant when creating a new image.
When exporting based on a previously imported image, the extension of that imported image will be used.
