The following page : http://nemo.bms.ez.no/sandbox/index.php/back/content/bookmark that is the page opened when clicking the Bookmarks link in the right area of the Administration Interface produces an error message about not having sufficient permissions when attempted accessed by a user belonging to the default Editor group.

Using and managing bookmarks should be part of what an Editor is permitted to do, since it is a valuable part of working with content. As far as I can see, this is the only item under My account tab that is not accessible by Editors.
