Wolfie:
It also says THIS:
Complete control over directly editing EPUB syntax in Code View
--and--
Full Regular Expression (PCRE) support for Find & Replace
--and--
Documents can be validated for EPUB compliance with the integrated FlightCrew EPUB validator.
Sorry, but just because something says "WYSIWYG" doesn't mean that the whole bloody THING works like magic. Taking a single word or acronym out of context doesn't support the idea that he should be able to use Sigil like WORD.
The BV editor
IS "WYSIWYG." The OP can absolutely go through, and
without ever looking at CV, make each of his chapter heads a header, in BV.
But he doesn't WANT TO DO THAT. He wants to have access to the
advanced features of using html--so he can regex (F&R/S&R) his incorrectly-coded headers so that he doesn't have to do it by hand. In the alternative, he doesn't want to PAY $40 to use Jutoh, which will do what he wants.
It ain't a perfect world. Like I said, learn or pay. Jutoh, Scrivener, AWP + a plug-in, OO + a plug-in, whatever--it's all going to either cost money or have a learning curve.
