"Do no harm" mode?

Hi all,

Is there any way to get sigil to not make ANY changes to the content, form, and structure of an ePub file when I open it?

I've never really understood the point of automatically moving moving stylesheets and html files into CONSTANT named folders (Styles, Text, etc) within the epub, even for a perfectly well-formed file.

My production process takes input files and outputs validated, well-formed ePub files. Sometimes I just want to make a small change to a one chapter without regenerating the whole ePub from source. When I do this, Sigil dramatically restructures and edits the ePub.

Thanks, even despite this (Relatively minor) issue, Sigil is a great tool!
