I have expose mode on. When I use expose mode I get the zoom out showing all my windows. This is fine. However, when I hover my mouse over one of those windows I get a title bar of what that window is. Is there a way to set it show it always shows the hovering title on all windows and not just when I hover over it? I have the compiz settings manager installed but didn't see any options in there to turn it on.
Open the Compiz Settings Manager and look for Scale Addons (confusingly in the Utility section, not with the regular Scale plugin under Window Management). From there, click on the Appearance tab and open the Window Title section. You'll find a drop-down menu for the Window Title Display, which you can change to All Windows.
I believe you might also need to have the package "compiz-plugins-extra".
In addition, as pydave mentions below, make sure that the Text Plugin (in the Image Loading Section), is enabled.
