"Save" -----> "Mark Version" I think the save button more or less provides a way to save a version or "mark" one. I don't want to see the button disappear, but rather change into a "mark version" button that allows auto-saving to happen, but gives the user the opportunity to set their own points of reference in a document's history. In software that auto-saves, I often feel a bit disoriented. It makes it harder to jump back to a certain state of a document.
