tcolorbox
I have found I am unable to use an equals sign in the titles of tcolorboxes.
\begin{tcolorbox}[title=foo\=bar]
\end{tcolorbox}
Using a normal equals sign messes with the parameter syntax, and using \={} causes it to be a high horizontal line over any subsequent character.
Is there any way to make it show an equals sign correctly?
Warning: I am no titlesec expert, but as far as I understood the 3rd. mandatory argument of a \titleformat is used for the vertical separation of the title. So use a negative value to shift up the title.
I introduced the \chaptertopspacing length variable and set it to the value of 130pt, this value is somewhat 'arbitrary' and should be changed to one's own needs.

\end{document}
The line \MakeRobust\mylib makes \mylib robust, so that you can use it in the argument of commands like \section or \caption. The line \pdfstringdefDisableCommands (used only if hyperref is loaded) makes \mylib produce a sensible PDF outline entry when used in \section. If you then do \section{Library \mylib{lipsum}} it won't break (because of \MakeRobust), and the PDF outline will say Library 'lipsum'.

\=is a macron accent command. In common with most other commands taking a key-value list, you can use braces to hide commas or equals signs in a value, so
