+Feature: Store the content bank view preference
+  In order to consistantly view the content bank in icons or details view
+  As an admin
+  I need to be able to store my view preference
+
+  Background:
+    Given the following "contentbank content" exist:
+        | contextlevel | reference | contenttype       | user  | contentname          |
+        | System       |           | contenttype_h5p   | admin | filltheblanks.h5p    |
+        | System       |           | contenttype_h5p   | admin | mathsbook.h5p        |
+
+  Scenario: Admins can order content in the content bank
+    Given I log in as "admin"
+    And I am on site homepage
+    And I turn editing mode on
+    And I add the "Navigation" block if not present
+    And I expand "Site pages" node
+    And I click on "Content bank" "link"
+    When I click on "Display contentbank with file details" "button"
+    And I should see "Last modified"
+    And I follow "filltheblanks.h5p"
+    And I click on "Content bank" "link"
+    And I should see "Last modified"
+    And I click on "Display contentbank with icons" "button"
+    And I follow "filltheblanks.h5p"
