LibreOffice 4.0 released

In my former job I was using MS office a lot, and never really got used to the ribbon, one of my main annoiances was like you said "They occupy way to much space vertically, a show-stopper in itself." - especially when working on a not-too-large widescreen laptop - but somehow I discovered that by clicking the bottom of the ribbon, it get minimized .- so then it was possible to Get Work Done (tm) - despite the ribbon. Just clik on it again and it is back to it old space-waste.
