Currently to view windows of the same application on the dash you need to click, then out pop the other windows.
How would I go about enabling this on mouse over? I wouldn't call myself a power user but it can be frustrating when I have 3+ windows open of Firefox etc, and I have to click every single time and it feels quite sluggish.
I tried having a little look with the GNOME Tweak Tool but couldn't see anything.
