 151     http://developer.gnome.org/projects/gup/hig/1.0/index.html
 152
 153 Please note: there are some differences between the Gnome HIG menu suggestions and our implementation:
 154
 155 File/Open Recent:   the Gnome HIG suggests putting the list of recently used files as elements into the File menuitem.
 156                     As this is ok for only a few items, this will become unhandy for 10 or even more list entries.
 157                     For this reason, we use a submenu for this.
 158
 159 File/Close:         the Gnome HIG suggests putting this item just above the Quit item.
 160                     This results in unintuitive behaviour as both Close and Quit items are very near together.
 161                     By putting the Close item near the open item(s), it better suggests that it will close the
 162                     currently opened/captured file only.
