Did they failed to present an acceptable transition route, or did it fail to satisfy a specific important use case, or did the interface not facilitate your workflow? I’ve done a ton of layout in InDesign and think it’s decent. I’d say the typesetting tools are fantastic, but it doesn’t exactly spark joy. I spent probably 12 hours total in PageMaker in a high school graphic design class 25 years ago, so I don’t have a real reference point. Curious what the tipping point was in your instance.
