I managed to install a new program in Wine, but it did not appear in the main menu. When I ran the Settings Manager/Main Menu editor, no changes could be made. Existing menu items could not be hidden or changed and new items and folders could not be added.
I could not find out the command for Main Menu and sudoed xfce4-settings-manager just in case it was a permissions thing and, of course, it did not show my user Main Menu editor.
New Linux programs are appearing in the menu, so I assume the menu files are created directly. I seem to remember .desktop files so I will investigate whether I can do the job, manually.
Has anyone else managed to edit anything in the 13.10 Main Menu editor?
