Welcome to the forum Vlackho
I'm pretty sure that can't be done.
To me it looks like you would need something like a 40 inch 8k computer monitor to have all that content displayed properly. (if you have that, I might be jealous ;-)
My guess is that this isn't something that would be very useful to most users.
edit:
Out of curiosity I checked if this guess of mine that this would be very difficult to achieve display-wise was correct, and it isn't.
When using e.g. a QHD or 4K display, and having MusicBee in full-screen mode and hiding most or all side-panels, something like the mock-up you created should be doable.
