For those of you building multiple applications, wanting to migrate only pieces of your old application, or wanting to duplicate blocks to other pages of the same application this one is going to save you plenty of time. 

If you have a block you want to duplicate, you can now do so across different applications and pages too. Just like you would duplicate a block on the same page, you will now also be offered the option to 'copy to another page'. Simply click the option from the menu bar, and select the application (and then page) you want to duplicate the block to! Smart.
