Adding some new settings related to showing just the page numbers on top of the score along with where it should be placed would definitely be easier. I'll make the placement configurable, and I may also add some options for having it be always present, versus fading in/out when the page is changed.
Another option would be to draw the page numbers on the pages themselves. I'm not sure if some people would prefer that.
