Every application that does syncing should support some notion of “revisions”.

It takes only one sync algorithm mistake or a bad conflict resolution approach to suffer data loss. As more apps become “revision-aware”, like Dropbox does so well, there’s many more novel things to be achieved with it, and this is one of them.

I very much agree that syncing and revision history should go hand-in-hand. It’s accepted that users make mistakes and need undo. It’s pretty clear that in syncing, the computer may make a mistake that needs undo as well.
