The problem is that there hasn't been a good interface to represent that change history, which will allow me to prune dead ends, and visually identify the version that I want to use to start again from. I can't identify that revision as "the one from 1:52 pm" because I don't know when the auto-save happened. What I do know is that I want the one where I used the phrase 'When Sally Met Harry' in the third paragraph, but not the one where I used it in the fourth paragraph.

Remember - it has to work for non-technical users, so saying "just make it work like Git" won't fly.
