Latex todonotes package set default to inline

Question

Is it possible to set the default style of todo notes by the latex todonotes package to inline to avoid mentioning inline everytime?

I imported the package into my latex document like this:

\usepackage[colorinlistoftodos,prependcaption,textsize=tiny]{todonotes}

and used it in the document like this:

\todo[inline]{New TODO comment}

Answer 1

Patching it into the original code:

\documentclass{article}
\usepackage{blindtext}
\usepackage[colorinlistoftodos,prependcaption,textsize=tiny]{todonotes}
\usepackage{regexpatch}
%\tracingxpatches%for debugging
\makeatletter
\xpatchcmd{\@todo}{\setkeys{todonotes}{#1}}{\setkeys{todonotes}{inline,#1}}{}{}
\makeatother
\begin{document}
\blindtext\todo{This should be inline}
\blindtext\todo[color=blue!20!white]{Is this blue?}
\end{document}

Advantage: You can still use any optional argument.

Answer 2

You can add more keys to the preset list:

\documentclass{article}
\usepackage[colorinlistoftodos,prependcaption,textsize=tiny]{todonotes}
\usepackage{blindtext}
\presetkeys%
    {todonotes}%
    {inline,backgroundcolor=yellow}{}
\begin{document}
\blindtext\todo{This should be inline}
\blindtext\todo[color=blue!20!white]{Is this blue?}
\end{document}

Answer 3

In newer versions of todonotes you can use \setuptodonotes to set default options.

\documentclass{article}

\usepackage{todonotes}
\setuptodonotes{inline}

\begin{document}

Some text.\todo{Improve text.}

\end{document}
