Cool, thanks.  I just launched the tutorial (butterfly) system minutes before you dropped by, so you&#x27;re the first user to try it out.  :)  You can turn it off from the help overlay, there&#x27;s a toggle at the bottom of the screen.  It&#x27;ll turn off for 2 weeks, then turn itself back on again -- but will only show up to tell you about features you haven&#x27;t used yet.<p>The diffs will automatically switch between one and two columns based on window size.  One of the butterflies would&#x27;ve told you about that.  ;)
