Other changes

What used to be the Inspector in MuseScore 3 is the Properties tab in MuseScore 4.
The tool to switch between page view and continuous view is now at the bottom right of the MuseScore window.
Same for the Zoom control.
Same for the Concert pitch toggle.
To (temporarily) change the playback speed you now need to undock the Play Panel.
The "Toggle MIDI" button now is behind the Play Panel's cog wheel.
Fermata is now in the Breaths & Pauses palette
Hiding an instrument now mutes it by default. However, you can now hide the individual staves of the instrument, which is more flexible.
The Text tool is now in the Text Properties, partly 'hidden' behind the More botton.

Missing Features

Due to the nature of the upgrade some features previously present in MuseScore 3 have not (yet) been included. See this page in the developers' handbook for a listing of those items.
