There’s no way Apple can build this. Their human interface people all seem to be gone on the desktop. So many things work so bad these days when they migrated to the new ui framework.
At the time Apple bought eMagic, Logic's UI sucked. It actually had dialogs that told you to "reboot the dialog for changes to take effect."
Given how well-regarded Logic is today, it must be drastically improved. I haven't looked at it lately, but am considering the bundle with Motion and FCP.
One piece of software Apple built in-house is Motion. While it suffers from a few UI gaffes, it was an innovative product that still has no competitor in the motion-graphics space.
