Comment 6 for bug 1403140

And another:

- I always had trouble with multiple windows of the same application, i.e. Firefox or Nautilus, upon clicking the dock icon and from there selecting the desired window in the overview spread, it would never appear on top if another one was maximized until I *again* clicked on the dock and *again* clicked on the desired window in the overview spread. Now with focus prevention turned OFF it all works perfectly.

This is like a major new bugfix release of Unity 7 now, resolving all the major annoyances I had with Unity... Thumbs up!
