title: noflo how to save changes in noflo-ui at the server
body: <p>i install <strong>node + noflo</strong> on my server and create a <strong>.fbp</strong>.
  now i start the <strong>ws server</strong> for the <strong>noflo-ui</strong> with</p>
  
  <pre><code>node node_modules/.bin/noflo-nodejs --graph graphs/test1.fbp
  </code></pre>
  
  <p>now i get an <strong>url for the ui</strong>. there i can make changes. 
  but this <strong>changes are not saved back to the fbp file</strong>.
  if i stop the node i lose all changes.</p>
  
  <blockquote>
    <p>i not have seen any save button.
    is there a method to save?</p>
  </blockquote>
  
  <p>is it possible to run more then one fbp file without starting an new server every time?</p>
