Using the Aftermath theme, where can I change the default fixed with at? I'd like to increase it just a bit. Sorry for asking what is probably a very simple template edit, but I'm not sure where to find it. =)
So unfortunately due to the graphical complexity of Aftermath theme, I have not been able to pull off a truly collapsible layout yet - however it does support full width mode (available via Style Properties -> [Nulumia] Theme Settings property group).
I am looking into converting the base theme coding to use the new full-width code by default, so it can be fluid. This is more due to the theme originally having been coded for fixed width.
