I have just set it all up as in this thread Trash XenPorta Sidebar. Very easy to do but just remember the first block "Clear Side blocks" only clears the blocks on the right where you want to place your Widget Framework Blocks. The blocks in the left and middle are still done in the XenPorta configuration. I have selected to not have anything in the left so I am just using the middle option from XenPorta
Actually for those that want to do this all I have now done is added new blocks into my Widget Framework using the code below in the Position option.
So now I have the XenPorta ones where I want them and the additions where I want those. I am only using the right hand blocks here
