Thanks so much for taking all this time and trouble about my small problems.
I have honestly never used a SW tool in my long professional life that was as well supported as this one is!
My status is that I have the content of my little book in place and am only doing some revising and tweaking. The PDF looks good. The epub is acceptable (with the table hack), so all I need is a fix for the misplaced div or whatever it is (Epub output errors in new 3.4. release). The fix has to be straightforward and I would expect a hot fix release couldn’t take long. So my plan is to publish both formats at KDP in early January.
I never could have achieved this without the outstanding support!
Whether I write another book after that, and how challenging that would turn out to be in Scriviner, I have no idea, but I have certainly learned a lot in the last two months! Thank you!
