Stabilty and Interface that don'change. And is a good program because the product don't need any plugins and stay stable for years

I use FlowPaper for publishing books and reading them, and I love its simple UI. It's totally free, which is a big plus for me. I really like that I can customize my book; it helps me change the page flip and the display when I'm publishing books. Setting it up was easy too, I just clicked 'Create now' and used the default settings that were good, and then it was done. I would totally recommend it to a friend or colleague, giving it a 10/10.
