Add a "Save as" Button
If you add a "save as" button, not only can you use it online, but you can save it to your H-Drive or what ever you need to save to.

Thanks for posting this idea.
You can find the "Save As" button by go to "File" -> "Save As" tab. This command will allow you to save a copy online.
If you want to save a copy to your hard drive, you can click the "Download a Copy" button on the same tab ("File" -> "Save As").
Hope this helps and please keep on posting!
