With multiple viewports, you can right click a window and then move it to the viewport right/down, etc.
On Gnome, I could send a window directly to workspace 1/2/3/4.
Can I implement this in Unity? Right click the window and send the window to a named or numbered viewport?
Right clicking on title bar gives options for moving to different workspaces. This functionality is already implemented in Unity and has been for some time.
