super+tab should work like alt+tab

Currently super+tab switches tabs in a circular way which is not really useful. How about making this behaviour more consistent and implement workspace switching like window switching? So, when I alt+tab, I switch to a previously active window, another alt+tab will bring that window back. If the same is implemented for workspaces it would be very convenient for fullscreen one window per workspace workflow, so that super+tab switched back and forth between current and previous workspace.
