Add tabs to a view-page
For "the view" you should add a menu style default menu tab with View URL: example.com/view/the-view and a parent menu item with URL: example.com/view.
For "the sorter" you should add a menu tab menu item and have the View URL be example.com/view/the-sorter.


This is easier to do than to explain. You might need to fiddling around to get it, but this is the gist of it.
