I'm using GNOME3 (under Ubuntu 16.04) and I actually like the ALt-Tab; Alt-^/` (key above Tab, varies regionally depending on the layout of the keyboard) bindings for switching between applications and windows of a specific application, respectively.
My concern is that ALt-Tab will take all windows of one application to the front whereas all I usually want and expect is the topmost of the windows from that application. How can I get this behavior?
