I find that my todo notes are cropped:
This seems to be the case no matter where I put the note. I think the problem might be the fullpage
package.
\documentclass[a4paper, fleqn, 12pt]{amsart}
\usepackage{fullpage}
\usepackage{amsmath}
\usepackage{mathtools}
\usepackage{amsthm, todonotes, color, amsfonts, hyperref, amssymb, tipa}
\usepackage{graphicx}
\usepackage{hyphenat}
\usepackage{arydshln}
\usepackage{subcaption}
\begin{document}
Lorem ipsum dolor sit amet,\todo{Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.} consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
\end{document}
Please help :)
The same problem arises with the following code and resolves when fullpage
is removed:
\documentclass[a4paper, fleqn, 12pt]{amsart}
\usepackage{fullpage}
\usepackage{todonotes}
\begin{document}
Lorem ipsum dolor sit amet,\todo{Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.} consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
\end{document}
fullpage
sets the margins width to be 1in by default. Use something like\usepackage[textwidth=0.75in]{todonotes}
instead?todonotes
on its own, with this option, instead of in a bundle as in your sample code?
