 160 /*  As a general GUI guideline, we try to follow the Gnome Human Interface Guidelines, which can be found at:
 161     http://developer.gnome.org/projects/gup/hig/1.0/index.html
 162
 163 Please note: there are some differences between the Gnome HIG menu suggestions and our implementation:
 164
 165 File/Open Recent:   the Gnome HIG suggests putting the list of recently used files as elements into the File menuitem.
 166                     As this is ok for only a few items, this will become unhandy for 10 or even more list entries.
 167                     For this reason, we use a submenu for this.
 168
 169 File/Close:         the Gnome HIG suggests putting this item just above the Quit item.
 170                     This results in unintuitive behaviour as both Close and Quit items are very near together.
 171                     By putting the Close item near the open item(s), it better suggests that it will close the
 172                     currently opened/captured file only.
