title: Add JumpList customized category with check box
body: <p>Basically, I want to add a JumpTask into the Jump List context menu that allows the user to toggle the TopMost property.</p>
  
  <p>Essentially I just want an entry that has a check box to turn the TopMost property on and off.</p>
  
  <p>How do I do this? It would be nice if the Jump Task could just be a stack panel of a CheckBox and a TextBlock, then I could just bind directly to those. However, the properties on a Jump Task are very limiting, and I was wondering if anyone's figured out a good practice to have a checkbox + text show up in a jumplist</p>
