If you’ve ever typed anything into a Google Doc, you can now play it back as if it were a movie — like traveling through time to look over your own shoulder as you write.

For a while now Google Docs, or Drive, or Docs Drive, or whatever they are calling it today, has recorded every update to a document by every user down to the microsecond. This makes it easy to recover any information you may have lost or to revert to an older copy of the document. Somers has used this data to make a “movie” out of your document updates.
