Thanks guys. I don't know enough to know how much I don't know
More specifically, many of the tools are written in Python, sometimes with PyQT, and I was wondering how that works with Windows and how smoothly integrated it is. Is it hard to do git pulls on Windows? What kind of build environment should I set up, the free MS Visual Studio Community or some port of GNU tools?
After reading a bunch it looks like I should switch to Kindle Previewer instead of kindlegen. And I meant Kindle Comic
Converter, not Creator, and that looks like Windows is a first class citizen for that.
I understand that Calibre hides a lot of this stuff from the user, but I specifically don't want to use Calibre because I have never liked it, neither its UI, nor its conversion, nor its editor.
Lately, I've been re-reading some old books and now regret my decision to change them into HTML or epub "someday" instead of right away. I even have a bunch of Peanut Press books I'm slowly changing to HTML haha.
