hide the Side Panel / Quick Launch area on the v4.master

On dashboard pages I often find I need more space.  A quick way to do this is to place this into a Content Editor Web Part.

1 <script type='text/javascript'>  
2  
3 function v4MasterHideSidePanel() {  
4 $('#s4-mainarea').children().eq(0).hide();  
5 $('#s4-mainarea').children().eq(1).css('margin-left', '0');  
6 }  
7  
8 $(document).ready(function(){  
9 v4MasterHideSidePanel(); 
10 }); 
11  
12 </script>

This will hide the Side Panel / Quick Launch area on the v4.master – Master Page (Default Master Page for non-publishing sites)

NB: This method relies on JQuery
