Autosave Documents / Objects possible?


Often our CMS users spend quite some time editing a Document or Object. And if for some reason the page refreshes all edits are gone. Is there a way to autosave the draft (or whats a good way to do that), without publishing? Where to create such a ‘autosave every 3 minutes’ ?

I would like it to be really saved as ‘autosave’ to also not pollute the versions every 3 minutes.
