I am using this code
\documentclass{book}
\usepackage{manyfoot}
\SelectFootnoteRule{A}
\DeclareNewFootnote{A}[roman]
\renewcommand*{\thefootnoteA}{*}
\begin{document}
Text 1\footnote{Normal footnote 1.}.
Text 2\footnoteA{Custom footnote 1.}.
Text 3\footnote{Normal footnote 2.}.
Text 4\footnoteA{Custom footnote 2.}.
\end{document}
and trying to eliminate the distance between the normal footnotes and the (*) footnotes. Also can I add some distance from the rule ?
