XFDASHBOARD: GNOME SHELL LIKE DASHBOARD FOR XFCE
While Xfdashboard was created for use under Xfce, it can be used in any desktop environment however, it has a couple of Xfce dependencies: xfconf and garcon.
The application is great for those who want the GNOME Shell Activities functionality (or at least most of it) under a light desktop environment such as Xfce, but there are two things which need to be improved: in my test, Xfdashboard was a bit slow when searching for applications and also, its design needs some improvements in my opinion. The latter might be solved by using a theme since Xfdashboard supports theming, but I couldn't find any themes for it. I see that the app is under heavy development so hopefully these will be solved soon.
