Some considerations regarding Continuous View
Recent discussion in other threads (see, for instance, https://musescore.org/en/comment/940716) suggest reviewing the very concept and implementation of Continuous view. In the corresponding handbook page, https://musescore.org/en/handbook/3/viewing-and-navigation, we find the following note: "Because the layout is simpler, MuseScore may perform faster in Continuous View than Page View". However, it seems to be the other way around in the current implementation.
What is continuous view intended for? Let's first comment that appart from educational and study applications, there are three main uses of MuseScore: 1) Transcribing engraved music, 2) Transcribing hand written music, 3) Composing music. In all three cases there are two stages: inputting the notes, dynamics and other symbols, and formatting the final score. For scores with very few staves per system, such as soloist music or chamber music, in which several systems fit on the page and on the screen, it may make sense to edit directly in Page view, especially in the case of engraved music. But when working on large scores such as large band and orchestral music, continuous view offers a distinct advantage: more music can be seen at a glance since no screen space is used for margins and page separation.
As in cotinuous view the page distribution cannot be seen, any attempt to format the music may be a waste of time. For that very reason, layout refinements for continuous view should be kept at a minimum and affect only the visible part or, at most, +/- one screen to facilitate scrolling.
Sometimes spacers are necessary, for instance, when the area between staves is overcrowded or when lower ledger lines from one staff collide with upper ledger lines from the next, to prevent input errors. However, they should affect only the current screen. When after scrolling a spacer goes out of the screen, its effect should disappear and replaced by the standard staff distance or by the effect of any spacer that could appear on next screen (or the maximum if more than one). The only undesirable effect would be that the vertical position of the next staff would change somewhat, but as the name of parts is shown at the left of the score window no confusion is likely.
