Looks good. Similar in principle to how a lot of newspaper production systems (Quark Publishing System/Quark CopyDesk, Atex etc) work - store major revisions alongside autosaves. One comment: the diff screen is a bit too programmery. "har" vs "av" is impossible to accept/reject just from looking at it - you have to parse the context and work out what the words are. "Sharing" vs "Saving" or "Insanley" vs "Insanely" is much easier to immediately yes/no.
