I'm using mhchem and I'd like to change the default length of the variable
\__mhchem_arrow_options_minLength:n
(It's on the line 1015 of the mhchem.sty file.)
What should I type in my preamble after
\usepackage[version=4]{mhchem}
to change this length?The developer of this package told me that there is no public API, so I could experiment with this variable.
Thank you very much.
