I have been trying to make a launcher with a quicklist item for 'root file browser' using command 'gksudo nautilus'. After I updated to this launcher in the unity sidebar, each time I click the icon (which still points to the normal nautilus for left click) a separate nautilus icon appears elsewhere in the sidebar with the title 'Files'. I really want it to appear under the same icon in the sidebar. I copied the nautilus-home.desktop from /usr/share/applications.
Here is the contents of the nautilus-home.desktop file in ~/.local/share/applications
[Desktop Entry]
Name=File Browser
Comment=Open your personal folder
Exec=nautilus
Icon=user-home
Terminal=false
StartupNotify=true
Type=Application
OnlyShowIn=GNOME;Unity;
Categories=GNOME;GTK;Core;
X-GNOME-Bugzilla-Bugzilla=GNOME
X-GNOME-Bugzilla-Product=nautilus
X-GNOME-Bugzilla-Component=general
X-GNOME-Bugzilla-Version=3.0.0
X-Ubuntu-Gettext-Domain=nautilus
X-Ayatana-Desktop-Shortcuts=Root
[Root Shortcut Group]
Name=Root File Browser
Exec=gksudo nautilus
TargetEnvironment=Unity
I hope this helps.
