Say you're looking at an old article, and you find a typo. How can you not fix it? So, you do so— but now your dang data is all screwed up as the article is automatically set to have been "updated." It now appears under the "recent articles" section on the world's homepage, and on your profile— no matter how small the "update" was.   Maybe you need to copy a section or container from one article to use in another, and because of the autosave, the act of simply clicking inside the editor has now changed the last updated date, and made the article "recent" despite you not actually changing anything.   Maybe the article you tweaked is a meta article you don't really want to show up on your profile or the world's recent articles list.   Maybe you're slowly editing through your articles from oldest to newest, or otherwise need to know that order as accurately as possible— and since the date change is automatic, you've just screwed yourself over by fixing a tiny typo.

  Either way, the automatic date-update often feels frustrating, and I think it'd be fantastic to have control over it. Perhaps a checkbox near the save button to toggle it on/off, or a switch in our user settings, could do the job? Maybe making it so the "last updated" date doesn't change unless we manually hit save could work, too.
