Another major improvement in WF2. And that is that solid/surface swap possibility when chosing extrude. Defaultis solid. So when sketching a open sketch you get the error message that the sketch should be closed. Oh OK, so I want to chose for surface without capped ends (and this is what I want in most cases). But WF2 wouldn't let met exit the sketcher to chose that options. It forces me to close the sketch, so I can sketch again. Or, close the section and redefine it again to open it. Boy!
