Return button for posts and threads.

Have you like ever worked on something and you accidentally did something to it, like deleted it? Well, a return button could solve the problem. Like in Google docs, we should have a return button that could return us to our previous steps of something. Also, a forward button would be useful, because if it was a just that return button, you wouldn't know how to go forward, maybe you skipped something or accidentally pressed the back button. So, what do you say?
