This is a huge Plank theme collection 107 plank themes in total and growing, they have been collected from various places around the web and integrated into one theme pack for convenience, I’ve only shown a few in the screen shots as there is to many to show in one place.
To install the Plank themes, copy the contents of the Plank Themes folder to ~/.local/share/plank/themes or to /usr/share/plank/themes for system-wide use. Now open the Plank preferences window by executing plank --preferences from a terminal and then select from the huge collection of themes.
Bugs should be reported here on the Github issues page.
Plank Themes is available under the terms of the GPL-3.0 license See COPYING for details.
Any suggestions for features and contributions to the continuing development can be made via the issue tracker or contributions via a pull request.
