I'm adjusting some text with \vfill and \vspace{}. I want a better orientation, so I think, that a package which displays a grid (or gridlines) over the hole page would be great. Or a package, what displays a X (corner to corner), to see the exact middle of the page.
Analogously to \usepackage{show frame}
UPDATE: Here my MWE, including everything, which is needed to solve my problem...
\documentclass{article}
\begin{document}
dummy
\end{document}
