[MU4 Suggestion] Home > Scores: Change layout

[PetJer]

Suggestion I had a thought about some changes for the Scores section in the Home tab:

Old:

New:

The difference

1. The "New" button in the lower right corner does the same as the blank page with a plus, it doesn't look necessary, so I removed it.
2. The "Open other..." button seems something more people would use (at least to me), so I made it similar to the blank page with a plus (just opens the file explorer).
3. I removed the "New & recent" text above the scores. Maybe it could be just changed to something like: "New/open & recent"

Thank you very much! could you add a small markdown file like the other notebooks have? just so people can see what's in there in case they don't have a jupyter running or aren't on github. it can be super brief.
