As you may know, Ubuntu After Install is an app created by the Faenza developers, which enables the users to install codecs, plugins and other apps with a few clicks only, from a simple GUI.

It provides a list of available software and all the user has to do is tick the packages he wants to install and press Install Now. Among others, it installs the Ubuntu Restricrterd Extras, Unity Tweak Tool, Faenza Icon theme, Google Chrome, Kdenlive, LibreOffice, Dropbox, VLC, Gimp, Darktable, FileZilla, Kdenlive, Handbrake, OpenShot, Scribus, Skype, Shutter and Steam.
The latest version available is Ubuntu After Install 2.6 Beta, which has been recently released, bringing changes and enhancements.
The software is good to install the needed software after a fresh Ubuntu installation.
