@dostovel Sorry to answer before my turn, but, there is a ‘hack’:
if you go to Window > New Main Window, then in that New Window, at the right side of where it says Scene, create a Linked Copy.
Then both Windows have the same Scene, but changes like disabling Collections, or changing the shading or whatever, only affect the one where you make the changes.
Proof of concept:

Maybe there is another way, but this is all I know.
