As you may know, Xfdashboard is a dash for XFCE (similar to the Unity 7 Dash) that displays an overview of open applications enabling the users to switch between apps easily, a workspace selector, an app launcher and a search tool. Also, shortcuts can be easily created.
The latest version available is Xfdashboard 0.5.92, which has been recently released, which brings changes.
The latest version of Xfdashboard is available via some third party PPA, so installing the software on Xubunyu 16.04 Xenial Xerus, Xubuntu 15.10 Wily Werewolf and Xubuntu 14.04 Trusty Tahr is easy.
All you need to do is add the PPA to your system, update the local repository index and install the xfdashboard package:
