I have some missing docklets in docky I used to use before. The most important one I remember is "Show desktop" which is important for me. I tried removing and installing it several times but no use I can't find it in the docklet's part of the settings.

I tried searching for something like docky-extras in aptitude and synaptic package manager and tried different terms and combination but seems like there is no such thing.

So how can I add the missing docklet?
