Plank is meant to be the simplest dock on the planet. The goal is to provide just what a dock needs and absolutely nothing more. It is, however, a library which can be extended to create other dock programs with more advanced features. Thus, Plank is the underlying technology for Docky and aims to provide all the core features while Docky extends it to add fancier things like Docklets, painters, settings dialogs, etc.
Plank-Themer is a small program that allow you to change Plank Dock themes without any additional consumption of resources. It allows you to change your themes quickly and easily. This small program was written in bash script but now it is available via PPA for frequent updates and easily installation.
