Re: Debian Jessie, gnome-panel no menu.
---- start cut
Whether you are using Unity or you have switched to gnome-shell, the
launcher icons on your old gnome-panel have now been replaced by icons
on a panel along the left hand side, known as the "launcher".
Unfortunately, it is not possible to add application launcher icons to
the top panel, nor is it possible to change the position or appearance
of the launcher panel that appears on the left (or, at least, not much).

Is It true? Gnome-shell as Unity does not allow launcher icons on top bar?
