Improve automatic repositioning of score during note input

Your idea

When entering the last notes on a page, the paper will immediately jump to the next page. However, this is often unhelpful if someone is trying to write the final note for all staves before moving to the next page.

I suggest that the paper, instead of advancing to the next page, advances to either the half position (as I dragged it over to in the video), or the three quarter position (in which three-quarters of the new page are showing along with one quarter of the first).

Problem to be solved

It is very frustrating to have to drag the paper back manually when I want to finish with all staves before moving to the next measure.

Additional context

Though it would solve the problem; I don't like to use continuous view, especially if I am working on a final engraving of a score.

Start by locating the score-view repositioning logic used when entering the last notes on a page, then trace how the next page is selected. Compare behavior that leaves the view at the half or three-quarter position, and confirm the chosen behavior while finishing all staves before advancing.
