title: display icons (or content) on mouseover
body: <p>In twitter, when you hover your mouse over a message a star and a reply icon appears on the right.</p>
  
  <p>Similarly, in facebook when you hover your mouse over to an update, the little 'hide' icon appears on the right also giving a little context menu.</p>
  
  <p>I want to have a similar approach in my project for drag &amp; drop handles. What I can decide is the what the most efficient way is it to accomplish this goal.</p>
  
  <p>is it that everytime I hover the mouse onto a div with an id, do I just inject the html with .append() or similar? or do I show/hide the already existing html.. or is there a better way?</p>
