Plank Dock has proven its usefulness on many occasions, whether we use Voyager, Ubuntu, Linux Mint or derivatives. The interface is modern and allows countless adaptations, does not complicate the operating system and helps you save time. What's more, it gives a modern Mac look to your operating system, turning it into something special and not at all old.
The utility can be installed on all newer versions of Ubuntu, but also on its derivatives: Ubuntu 18.04 Bionic Beaver /16.04 Xenial / 15.10 Wily / 14.04 Trusty / 12.04 Precise / Linux Mint 17.x / 13 /. The installation is done using the Terminal and only takes a few seconds. More than likely, once installed, it will change for the better the feeling that your GNU / Linux distribution leaves you, proving irreplaceable.
