Getting a Better Expose under Unity

When you enable the Expose-like feature under Unity (Default Super+W), you'll see all of your windows tiled about the screen, allowing you to pick them easily.

The more windows you have open, however, the smaller the preview windows become. The fact that almost all applications have a fairly consistent look and feel might be good for the general desktop experience, but it's not very good for picking out which windows belong to which application.

One way to get around this is to overlay the application icon on the window itself. Unfortunately, the Unity itself doesn't have a configuration UI for this, so you'll need to do it at the Compiz level. To do this, install the package compizconfig-settings-manager:

apt-get install compizconfig-settings-manager

Now run the command, either using the launcher or typing "ccsm" into the terminal. Go the conrol panel called "Scale" under "Window Management", and set the "Overlay Icon" option. I personally prefer "Emblem", as it makes it easier to pick out the icon.

Voila, usable Expose.
