Created attachment 9902 New Item created at startup Impossible to hide Dropbox icon from Status Notifier Plugin. A new item is created every time the system is booted. It should be only one item. This way the user could select it for hiding once and it wouldn't be displayed ever again, unless user enables it again in the panel options.
This is certainly a problem with dropbox, not with the panel. If a new item is created each time dropbox starts up, there's nothing we can do about it...
Even though Dropbox creates an item each time at startup, it's possible to hide the icon by default by checking the tickbox "Hide items by default".
