Comment 7 for bug 333517

I would like to add these animations are also very effective on darker themes. Example, I was focused in the left side of the screen searching for an application in the menu and I did not observe the notification appear, but it caught my peripheral vision as the closing animation faded off the screen. Possibly enabling an opening animation or at least making that customizable would also have a great usabilty factor.

I am using Dylan's version from bzr trunk.
