Comment 16 for bug 763230

I agree.

But here is one thing I encounter in my system with Nvidia proprietary drivers that I don't encounter other systems I use. When I click an app's icon on task panel, it will display current windows from that app. And when I click it once more, all windows will be minimized.

This sounds wonderful, but here is the catch : then all of the minimized windows are lost but the most recent one you used. They just disappear and even super+w will not bring them back.
