Thats what I kinda mean, what if I don't want those documents to be there? What if I just want a clean session. From what I read in that link, Cmd+Q closes the app just like before, but it auto saves the file. What if I don't want it to auto save? From what the link said, the only way to not have it auto save is to close the window of the app, choose not to save when the dialog box comes up, and then close the program using Cmd+Q/File - Quit.
From what it sounds like, closing an app is now a two step process. Close the window of the app first, then File - Quit / Cmd+Q.
