Up and Down buttons

Thank you ,was wondering why we did not have them like NWKA

We do now.

My question is, why we don't have the option to view all posts of a thread on a single page.  Some other forums have this option and I've always kind of liked it.

For example, if a thread is 5 pages long, you can click on any page to read or click all and the thread opens as one page.  It's especially helpful when you're looking back trying to find specific info and not have to toggle between pages.
