Currently, the back button operates in a browser-like fashion. It walks back through a stack of visited locations.

In other GNOME applications, we generally have a level-like behavior: there's a number of main views (generally, the ones that have a button in the view switcher in the header bar, plus maybe a search page), and if you go to another place, the back button will get you back to one of the main views.

In places where we have 'browsing' (e.g. categories in gnome-software, or the chef and category pages here in recipes), we may have a two-level back button. You get from a detail page back to the category and from there back to the main view.

Jakub suggests that we should switch recipes to the level-like behavior. As part of this, we would change the search page to be an 'implicit' main view (ie without a button in the view switcher).
