3. See error

Expected behavior
All files are shown in the same workplace (see screenshot from MuseScore 3)

This is by design. With MU4, you can't have two files in a single instance

[LMGMMel]

Can you explain me why you chose to design it like this exactly? I really liked the feature which enabled me to switch between different files quickly.

[HemantAntony]

I'm not 100% sure why, But one major reason was to enable compatibility with VSTs. You couldn't do that in the old design

[cbjeukendrup]

Yeah. This is currently rather a technical limitation than a deliberate design choice. I still hope that we can overcome it in the future.

Since this issue is essentially a duplicate of #12647, let's close it.

You can switch between files quickly in MU4 using Alt+Tab, just as you would for switching between files in any other application that opens multiple windows. Or for switching between multiple applications, for that matter. At least, Alt+Tab is the shortcut in Windows and most Linux systems. I assume macOS has something similar, perhaps Cmd+Tab.

You can also snap both windows side by side
