I just realized the :sba or even better the :vert sba command. Is it possible to hide all windows again except the active one, which the cursor is in?
And another question: When I set the all windows to "scrollbind" and make jump to a special line, I want each window to show that line and not the offset to the original line. One solution is to do :windo normal gg and then :windo set scrollbind but is there an easier way?
