I couldn't find the setting so I guess it's not a feature yet? In fantastical, I can set it up so that only 12 hours appear in week view, this ensures my "workable" hours are only visible, and night time requires scrolling a little bit up or down. It's a much better use of screen real estate. On large screens, I see almost 24h in savvycal, and it can actually mislead me having a quick glance. Could there be a feature where by default only the working hours range fill the view (with the opportunity for users to scroll up or down)?
