quicklist in 15.10

I found that I was able to set up a quicklist for the Unity launcher in Ubuntu 15.10 using the same type of approach that I've used in the past in Ubuntu 11.04 (see "unity quicklists"), Ubuntu 12.04 (see "shaping up") and Ubuntu 14.04 (see "trusty screenshots").

First, I created ~/.local/share/applications/utilities.desktop:

[Desktop Entry]
Version=1.0
Type=Application
Terminal=false
Exec=
Name=Utilities
Icon=/usr/share/icons/Humanity/categories/48/applications-other.svg
X-Ayatana-Desktop-Shortcuts=Chromium;Nautilus;GNOMECalculator;Characters;Screenshot;Geeqie;Mirage;UnityTweak;SystemSettings;Synaptic;

[Chromium Shortcut Group]
Name=chromium
Exec=chromium
TargetEnvironment=Unity

[Nautilus Shortcut Group]
Name=nautilus
Exec=nautilus
TargetEnvironment=Unity

[GNOMECalculator Shortcut Group]
Name=gnome-calculator
Exec=gnome-calculator
TargetEnvironment=Unity

[Characters Shortcut Group]
Name=gucharmap
Exec=gucharmap
TargetEnvironment=Unity

[Screenshot Shortcut Group]
Name=gnome-screenshot
Exec=gnome-screenshot -i
TargetEnvironment=Unity

[Geeqie Shortcut Group]
Name=geeqie
Exec=geeqie
TargetEnvironment=Unity

[Mirage Shortcut Group]
Name=mirage
Exec=mirage
TargetEnvironment=Unity

[UnityTweak Shortcut Group]
Name=unity-tweak-tool
Exec=unity-tweak-tool
TargetEnvironment=Unity

[SystemSettings Shortcut Group]
Name=unity-control-center
Exec=unity-control-center
TargetEnvironment=Unity

[Synaptic Shortcut Group]
Name=synaptic
Exec=synaptic-pkexec
TargetEnvironment=Unity

Then I found the Utilities icon in the Dash and dragged it to the Unity launcher. Changes to the utilities.desktop file take effect immediately upon saving the file. Screenshot:
