After switching away from a 5 monitor setup to just using a laptop I began using multiple workspaces. As a vim user the default Ubuntu key bindings left something to be desired so I remapped them so that Alt-(h|j|k|l) move around in workspace... space and Ctrl-Alt-(h|j|k|l) move the current window similarly.

I am surprised that after enjoying multiple monitors for so many years, this way of working fits me well. I have been using this setup for more than two years now.
