Description of the need Pseudo fields clutter up the "Manage Fields" page. See https://github.com/backdrop-contrib/xmlsitemap/issues/56

Proposed solution Can we move these fields all to a vertical tab, or at least group them separately somehow, to differentiate them from the regular fields while still allowing re-sorting?
