Hi @howdoyoumex,
Navigation layout can be changed at Customize > Header > Primary Navigation.
To have the language switcher at the end, you can add the language switcher at the menu. Many of the multi-lingual plugins provide this. You can check at WP-admin > Appearance > Menu.
To have a different layout than this, you can create a new header using Elementor – https://docs.elementor.com/article/335-create-headers-using-elementors-theme-builder.
Hi @howdoyoumex,
The latest update of Neve has a new header/footer builder that should allow easier customizations. Let me know if you update and how do you feel about the builder.
Regards,
Rodica
