QT Creater designer tab is greyed out

Hi,
I don't know if this is the expected behavior. I created a new QT Quick application project. It shows up a main.qml and main.cpp file. The problem is the design tab is greyed out.

Yes, I think that's the expected behavior; that plugin is deprecated. You should use Qt Design Studio for designing your UI whilst Qt Creator to develop your business logic.
