title: jQuery FileUploadUI Single File Upload
body: <p>im using fileuploadui (<a href="https://github.com/blueimp/jQuery-File-Upload" rel="noreferrer">https://github.com/blueimp/jQuery-File-Upload</a>) to upload files for my website, but i would like to make it to upload to only 1 file, and not multiple.</p>
  
  <p>i have removed "multiple" from the input html tag (input type="file" name="file"), but the queue is still accepting more than 1 file.</p>
  
  <p>what i have in mind is that, whenever someone clicks on the "Browse File" button, it will replace the current queue with the new file. it will be forever 1 file in the queue.</p>
  
  <p>how do i use the replaceNode function ?</p>
  
  <p>thanks.</p>
