I am looking for something like what this gnome-shell extension offers. That is, I would like to see the icons of the applications in the spread mode. Is it, in anyway, possible in Unity?
After roaming around in CCSM, I have found what I wanted.
Go to Scale under Window Management and choose either Emblem or Big for Overlay icon.
The emblem option gives you a small icon on the lower right hand side of the application while the Big option shows a big icon filling the entire application.
