Plank-Themer is – as the name suggests – a small program with which you can easily change the theme of your Plank dock. You can easily install it to any Ubuntu based distribution, for example Linux Mint or elementary OS. It creates an entry in your Plank dock and when clicking on it it shows the installed themes. See it in action below (screenshot and videos).
Installation

sudo apt-get install -y xterm
