Proposal

MVC 1	MVC 2
Move scroll arrow to the left of the action buttons	Move the action buttons out of the scrolling tabs list, and add it to a search/filter bar:

Implementation plan

We are going with MVC 1

Modify the CSS and markup in https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/views/admin/users/_users.html.haml#L9 to match the designs

Possible next iteration

Convert tabs into filter dropdowns, or add filters to searchbar similar to issues list 🤔
