Just finished the first seminar for the Jetpack for Learning competition. I was inspired to try out a quick-and-dirty take on our "notebook" idea from the original concept. If you have Jetpack installed, drop this in the Develop editor window and try it out.

jetpack.future.import('selection');
jetpack.future.import('slideBar');
jetpack.selection.onSelection(function(){
  var html = jetpack.selection.html;
  jetpack.slideBar.append({
    html:html,
    width:300
    });
});
