I would like to see in a future version of Pulse an implementation of a Copy or a Save As button for Pages and Blocks.
Many times I had to create similar Pulse Pages and Blocks for a website. My quickest workflow is as follows : I download a source file to my PC, change the filename, change the content and then upload the new file to the server.
Such a button will improve my workflow and will also give a site-editor (the client) an easier way to prepare a new page and/or block for their website.
