Draft Button

As you can see in the picture below, there's this new button draft. It is used for canceling posts or messages. Once you used it, your post drafted will be recorded at the draft tab in your profile. If you click the modify button, you will have the chance to modify it. There's three options at the modify drafted post page: preview, publish, and modify. The preview button is pretty familiar to all of us, so I won't be explaining it. The publish button gives you the chance to publish the drafted message while the modify button allows you to modify the text but not publish.
