Hey,
Minifying css is for speed. Since it’s never encouraged to write in a theme css file anyway but to use a child theme. If you wish to see the css unmified you can use this great tool: http://unminify.com/
All bowsers have inspect tool so you can see what css is effecting each element in readable css even if the css is minified. So overriding css is just a matter of copying that inspected css into a child theme or the theme options.
My minifying css we wanted to help users not offend them.
As for the citrus error, Thanks for pointing that out. It is set in the citrus skin and the css to change is:
.mobileclass.collapsed {
background: #000;
}
I will update a fix in the next version.
