title: resize vim viewports automatically while switching them
body: <p>How can I get vim to automatically change the view-port width while switching view-ports?</p>
  
  <p>Lets say I am looking at 5 files simultaneously. I have set my left view-port width to 80 column. When I rotate across viewports (<code>ctrl W + r</code>) I would like my next file to appear in my left view-port and with 80 column width.<br>
  Opening multiple files and switching (<code>:n and :prev</code>) is not an option as i want it integrated with my cscope tags.</p>
