Previously saved versions of a document
It would be very helpfull if InDesign stored a log of previously saved versions of one particualr document. For example, if I have worked on a file for multiple weeks and oversaved all of the changes that were made to the document, but then suddenly the client wanted to have some of the changes undone I could easily find the version where those changes hadn't been done. That would save the hassle of saving multiple documents or whole buch of additional pages inside the document.

I second this. We either have to Save As every time we Save, or never close the book/docs. Google Docs has this simple feature, shouldn't InDesign?
PS We would have to pay $15 to get this feature as an add-on/plug in when it's already in every other publishing type program on the market.
