Adding 'teamwork'
2 people able to work on the same score at the same time with real time stuff like google docs or google slides, for example. Stuff like play back will be activated at the same time for both people if one person presses it, but, stuff like opening a palette will not open it for both people.
Comments
Nothing explicitly in the application, but you might try a meeting software (Zoom, etc) and one of the "attendees" shares their screen with MuseScore running.
