What Is Docky?
Docky is an advanced shortcut bar that sits at the bottom, top, and/or sides of your screen. It provides easy access to some of the files, folders, and applications on your computer, displays which applications are currently running, holds windows in their minimized state, and more.
To install Docky from a terminal, use the commands below
sudo add-apt-repository ppa:docky-core/ppa
sudo apt-get update
sudo apt-get install docky
Docky will be added under Accessories in the Applications menu.
When you first launch Docky you will get a pretty simple dock on the bottom of your screen. You can drag and drop your application icons to rearrange them, and drag applications from the applications menu to Docky to add them. Pull an icon from Docky out and it will disappear in a puff of smoke.
