Yeah I know. We've had this discussion before. I just produced my fourth book using Designer Pro for the entire process. And while I might have more typographical control in InDesign, or Quark, I worked with a program with which I am conversant and I am very happy with the results. I don't think anyone reading the book is going to say, hmmm? this book was not created in InDesign. My hope is the typography will make the reading experience positive.

This is not to say that Designer Pro X is not ready to be rebuilt from the ground up as Affinity claims, it just works for me.
