virtual workspaces is what i am using now. trouble is that on a dual monitor setup that does not work very well, because either both workspaces move on both monitors at the same time (like kde does) or one monitor is static and only has one work space (like gnome support). the latter is slightly better, but wastes space because i can only organize one screen into multiple workspaces.

there are few window managers/ wayland compositors that do that right. enlightenment is one, but i couldn't get used to it. wayfire is a new compiz style wayland compositor that does it right too. loved that one, as i was a fan of compiz before (and i got wobbly windows with kde now too :-) but unfortunately not stable enough for daily use.
