Is there a better package to add comment / annotations into your LaTeX pdf than pdfcomment today?

Question

I am aware of the How to annotate PDF files generated by pdflatex? thread where the pdfcomment package is suggested. So this question is simply about whether you think this is still the best option for adding writing-up comments and self reminders as you go.

I just want to add notes here and there to remind myself to go back and finish up certain sections as I go through writing the next few sections. I quite like how the Microsoft Word comments look, is there something similar maybe?

Answer 1

I just want to add notes here and there to remind myself to go back and finish up certain sections as I go through writing the next few sections.

Sounds like stuff you want to do later and add a note for yourself. Package todonotes helps you with exactly that task.

\documentclass{article}
\usepackage{blindtext}
\usepackage{todonotes}
\begin{document}
\section{Introduction}
\blindtext
\todo{Don't forget to put a real introduction here.}
\end{document}

The package can create a list of all notes for you. If the global option disable is used, no notes are printed. A lot more to discover in the documentation. See texdoc todonotes.
