The questions and answers regarding wide paragraphs are rather popular. What I would like to have is a new kind of "element" in my documents which would allow me to display wide paragraphs which can contain text, picture or tables... The layout is shown on the picture. My own solution is rather trivial - it works but it has two major issues:
- It throws ton of overfull hboxes
- It could "mix" with marginpar text (puts it one above the other)

%PREAMBLE STUFF
\newlength{\wideparwidth} %The width of our new element
\setlength{\wideparwidth}{\textwidth} %Initializing to textwidth...
\addtolength{\wideparwidth}{\marginparsep} %adding marginsep...
\addtolength{\wideparwidth}{\marginparwidth} %adding marginparwidth
\newcommand{\widepar}[1]{\parbox{\wideparwidth}{#1}} %The actual command
%USAGE
\begin{document}
...
\widepar{The text which appears in the very wide paragraph...}
...
\end{document}
Is anybody aware of some existing package where such layout is supported? If not, please give me some tip how I could prevent marginpar text to overlap (I assume this is not trivial). And the last but not the least, how could I make "overfull hbox" ignored (for this element only)?

\makebox[\textwidth]{...}as shown in my answer to Place figures side by side, spill into outer margin. No idea about the marginpars. – Martin Scharrer Apr 18 '11 at 13:05\makebox[\textwidth]{...}and then place something wider than\textwidthinside. This way the overfull hbox warnings are avoided. – Martin Scharrer Apr 18 '11 at 13:29
