Separate exposed sort form from exposed filter block Is is possible in Drupal 8 Splitting exposed filters and exposed sort &amp; pagination i.e. placing sort &amp; pagination inside a separate block and filters in another block? 

Right now there is no out of the box solution to this. In my opinion this would greatly improve user experience.
I didn't see solution for such issues.
But I solved these issue with custom form elements and using the hook_views_query_alter.
In the hook_views_query_alter you can alter orderBy property.
