No no, Sigil exacerbates nothing. Sigil is not the problem. Sigil could be the solution.
I am evaluating the -huge- possibilities given by the new Sigil features "saved searches" and the clip editor (not to speak about "unused classes").
I can now perfect a check-list and try to improve my style-sheet.
You are right, my stylesheet is made by a converter. It's very handy and hassle-free. On the other hand, it's verbose and not nice-looking.
Another example that comes to my mind: I have way too many
font-family., one for every style (I use embedded fonts). I already placed the biggest one in
body and I have no problem. I only attribute a font to a style when it's a very special one (like smallcaps or Display).
I will try to simplify this way, item by item.
Edit: I did a careful trial but I surely missed some fine points. The resulting EPUB had a lot of defects. Putting a style sheet in order is not for the faint of heart... So for the time being, I keep my style sheet as it is.. Verbose but working.
