Stage Manager works beautifully for me, my iPad is my primary computer, and I use it for professional graphic design work, 3D modeling/sculpting, and all of my other workflow. I don’t think some Mac users will ever be happy with iPadOS, they just want iPadOS replaced with macOS. Also, the new Control Center will streamline many workflows with the ability to pin my custom Siri Shortcuts into it, as well as third-party apps providing controls for their apps. And Apple Intelligence looks like it will be revolutionary for multitasking.
