I’ve noticed this one boggling a few people and a few are frustrated that you can’t just right click and delete from the Gnome Panels Places menu.
To remove the shortcuts which are actually stored as bookmarks within Nautilus (the Gnome file manager), click Places, then click Home Folder. From the dropdown list, click Bookmarks and then click Edit.
Changes you make here directly affect the Places dropdown.
Perfect, man, thanks for this tip! 😉
