I'd like to edit the scaffolding file - is it possible?

I notice that I begin each project with a standard css file which is
the one produced by scaffolding PLUS some other stuff. I could cut
and paste a copy from an old project but I thought it would be
“cooler” amongst other things (like more efficient) to just have the
scaffold.css file be created for me.

Is it possible? Is it safe(ish), What would I have to do?

Thanks in advance,

bruce

I don’t know if it would be overkill or not but it’d be nice to have a
generator that generated a nice CSS to start with instead of the
scaffold CSS one. Maybe something with more goodness in it =)
