Is it possible to add a "new posts" link to the top bar (the one with "Home", "List All Users", "Search" etc.)? That would bring up new posts a person hasn't read without having to scroll through everything.

Also is it possible to add an "edit" for a post that you have already posted to? That's in case a person wants/needs to correct a spelling or grammar mistake or simply wants to add something to a post. The only person that could do this editing would be the person that posted that particular post.
