How to use legacy windows (Project window, Piano roll window, etc.)

I’m Cubase 9.5 user and don’t know when Cubase’s windows design was changed to several floating windows.
(Mixing window, Piano roll window, Project window, etc.)

I used Cubase 7.5 and it was not floating windows.
(All windows are not independent.)

I wonder if there is an option to go back to Cubase 7.5 (legacy) windows.


No, there is no way to go back to the old window concept.
