In Ubuntu 12.10, if I have multiple windows of an app, the first click on an icon brings the app window that is focused into view, and only the second click brings up what Ubuntu calls the spread here: http://design.canonical.com/2012/03/task-switching-in-ubuntu-and-a-introduction-to-the-spread/
As someone who just switched to Ubuntu from Windows XP, which effectively gives me the spread in one click, I find this slightly annoying. Is there a way to change the preferences so that the spread comes up on the first click, not the second?
