Introducing workflows that are essential for Finale users, which we also think will benefit all users of the app.

I quote:
With MakeMusic's announcement in August that it will be discontinuing Finale's development, we understood the need to provide a free and attractive alternative to people wanting to migrate to a different application. We took the opportunity to reach out to Finale users to learn what features they couldn't live without, and have set about making our own equivalents – tweaking them here and there to ensure they integrate comfortably with our own app.

In MuseScore 4.5, we'll be introducing:

• The ability to move measures to the previous/next system (using shortcuts or the Properties panel), allowing you to fit as many measures as you want within the same system
• The ability to lock systems so they remain as a single unit without reflowing when you make changes elsewhere on the score
• The ability to drag measures (or range selections) to quickly copy and paste them to other measures
• A new note input mode comparable to Finale's popular "Speedy Entry" system, which provides people with another way to quickly enter pitches and durations using their keyboard and (optionally) their MIDI keyboard too
  • Not only are these features beloved by Finale users, we also think they'll greatly enhance the workflow of all MuseScore Studio users too.

How can he elaborate on something presented by the musescore team?
Shouldn't you rather ask to the musescore team to elaborate?
