I thought the whole purpose was to end up with WYSIWYG - what you see is what you get. I type in Libre Office, I don't do anything stupid and weird, and when I tell it to save as an HTML file, it converts things. Maybe with more code than some of you guys like, but it's still fine. That way, when I load the HTML document up into Sigil to create the EPUB, all I have to do is scroll through and make sure things are fine.
Chapter One - yeah, that's okay. Halfway through Chapter Two - why did you just randomly change font color and start adding all sorts of extra crap, such that it took me over an hour to get it cleaned up? Chapter Three, you made it until the last three pages, then did the SAME THING! QUITE annoying to have to open a text window, copy paste the paragraphs from my ODT file into the text window with the appropriate HTML already in place, then copy and replace, one paragraph at a time, 22 pages.
And then the rest of the book was fine - no extra code, no random color changes, life is good. What the hell?
Okay, venting over now. Letting Flight Crew run for a while to see what it comes up with.
