Version: unspecified (using KDE 4.5.0) OS: Linux Dolphin currently supports service menus in the same way as Konqueror, through .desktop files in the share/kde4/services/ServiceMenus. However it does not support Konqueror popup menu plugins (ServiceTypes=KonqPopupMenu/Plugin). These are particularly useful for dynamic menus and submenus with content and labels that depend on context information beyond the selected items. Typical example is version control (hence the version control plugin since kde 4.4) and comparison programs which require to memorize previously selected file to compare with.
