# reverse todonotes side without changing chapter number placement in classicthesis

When using todonotes with classicthesis, my notes appear on the wrong side. I have added the options \let\marginpar\oldmarginpar and \reversemarginpar to my preamble but when I use \reversemarginpar it also reverses the placement of the classicthesis fancy chapter numbers. Is there a way to reverse the side of todonotes only, without messing with the classicthesis formatting?

\documentclass{scrbook}
\usepackage{classicthesis}
\usepackage{todonotes}
%\let\marginpar\oldmarginpar
%\reversemarginpar
\usepackage{showframe}
\usepackage{blindtext}
\begin{document}
\chapter{a duck section}
\blindtext
\todo{a note}
\end{document}

• Seems like a bug, please inform the author of classicthesis. – Johannes_B Oct 30 '14 at 8:56
• As this uses an scr class, you might be able to redefine \@todonotes@drawMarginNoteWithLine to use a note column instead. – Andrew Swann Oct 30 '14 at 8:57
