Already using that 
but the way gnome handles workspaces is not satisfying on multi screen. I am looking for a similar behavior to i3wm. Somehow it only lets me choose one screen as the master screen, the other one can only extend one workspace at the moment. As opposed to multiple workspaces that work independently on both screens.
Also the overview mode doesn’t show several workspaces on both screens. Don’t know if that expresses better my small beef with gnome.
Will try to see if I can screenshot.
