Additional Options in Authoring

The forms that I'm adding are long and at times tedious. It would be tremendously helpful if, when in the authoring section, you could "undo" something - like deleting a field or changing a participant. It would also be extremely helpful to have a "Save and Close" button. There are times when I need to come back to a document later and if I click off an open doc and go back to it, all of the tags are gone. I feel like there should at least be an auto-save feature. And while I'm thinking about it, it would be great if I could go back to the send page from the authoring page - sometimes I forget stuff and without this ability, I have to start the process all over.

Unless I'm missing something, but I can't seem to find out how to make any of the above work.
