Retaining the History of project even after closing and then reopening the same project

Though Photoshop is a great tool but I think it would be great if we could retain the history of a project. I would make myself clear this way... If I'm working on a project and for the reason I have to save and quit the application. when I return back and reopen the same project all the previous history is gone. It starts where I left off but still the history is all blank no details of previous session.
