I have write definitions in this way (this is a MWE class unatesi is available here):
\documentclass[laurea,oneside,12pt,italian]{unatesi}
\usepackage{amsthm}
\usepackage{thmtools}
\newtheorem{defin}{Definition}
\begin{document}
\begin{defin}[Definition's name]
Lorem ipsum dolorem
\end{defin}
\listoftheorems
\end{document}
So when list is printed, it shows something like that:
1 Definition (Definition's name)............................ 1
But I want something like
1 Definition's name............................................. 1
There's a way to do this?
