Forum drop down menu

Just a suggestion I don't want to upset the apple cart , another forum I use has a drop down menu that stays there no matter where you are on the page, I find it lots easier to navigate especially when there's 10 post or more, the forum software is same as here so it should be possible,

Could it be implemented without altering other things, I know some peeps don't like change, if it could be put in place without altering anything else members could use it/not,

This is a screen shot the new posts etc is permanently there so no need to scroll to top of the page/press the back arrow.
