List indicator

Launcher list indicator is a tool that gives you the possibility to create sets of unity launchers that can be easily changed.

To install Launcher List Indicator, you can use the main WebUpd8 PPA. To add the PPA and install the indicator in Ubuntu, use the following commands:

sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt update
sudo apt install launcher-list-indicator

If you don't want to add the PPA, you can download the deb from HERE.

Once installed, launch it from Dash.

To have Launcher List Indicator start automatically on login, you'll need to add it to startup. To do this, launch "Startup Applications" from Dash, click "Add", enter anything you want under "Name", and use "launcher-list-indicator" in the "Command" field.
