title: Store filter state for returning later
body: <p>I have an app with an index view and a show view, nothing special. The index view has filter options. What I want is that the filter options a user choses are stored in some way, so when a user opens the details screen and returns later, the same filtered records are shown.</p>
  
  <p>The back button is not an option, because there can be done more than just opening the details screen and returning. I could add the filter params to every request made afterwards until returning to the index page, but that seems to be a bit cumbersome. What are my options?</p>
