title: Drawing directly on personal wiki
body: <p>Is there any existing wiki support direct drawing function?</p>
  
  <p>Perhaps it is not a good idea for a well formatted wiki, how about a personal one?</p>
  
  <p>People nowadays using finger(tablet) or pens much often than keyboard,<br>
  a <strong>quick sketching</strong> is sometimes much easier to describing concept.  </p>
  
  <p>(import picture sounds not a lazy solution)</p>
  
  <p>Thanks!</p>
