Contemporary music notation palette

Your idea

As a composer and educator, I have a vested interest in the future of MuseScore, as probably over 90% of my students are now using it. While it has some incredibly advanced aspects (microtonal accidentals), there are some basic contemporary music notation areas that are still lacking or underdone. With a 'contemporary notation' palette, MuseScore could lead the way in this area.

While there are many things that could be added here, I have considered only the most common, important notations that would be needed and that have previously been requested. Some of these can already be achieved or 'hacked', but having them here would streamline their use.

I used the following criteria when coming up with a potential list:

1. Notation should still be in common usage, and should be present in important, published scores by leading composers
2. Notation should be 'feasible'/practical — I can imagine how it might be implemented, and the parameters necessary for completing it
3. Notation should either not already be present in MuseScore, or is present, but requires a bit of adjustment in order to achieve what I'm interested in

Here are my suggested symbols:

1. Aleatoric box, with option for extender line with arrow (line can be straight/curvy, arrow can be a vertical line)
2. Time bracket, with editable text
3. Duration indication, with editable duration
4. Technique transition arrow (already exists, but needs fiddling/adjustment)
5. Note-to-noise transition arrow (after Saariaho)
6. Bow pressure triangle (after Saariaho)
7. Sinewave vibrato/gliss diagram
8. Variable sinewave vibrato/gliss diagram
9. Squarewave smorzato diagram
10. Play between bridge and tailpiece (after Penderecki)
11. Play on tailpiece (after Penderecki)
12. Play on bridge (after Penderecki)
13. Play between bridge and tailpiece (after Penderecki)
14. Irregular non-rhythmic tremolo (after Penderecki)
15. Cluster block (after Penderecki)
16. Cluster chord
17. Notehead extender line (somewhat possible with note-attached lines; this just simplifies creation)
18. Woodwind fingering diagrams

Problem to be solved

A number of these are fairly standard notation these days, and would be amazing be included in future version of MuseScore.

Prior art

Dorico has a number of these features available.

Additional context

Each of these probably represent a significant amount of coding. They could be gradually introduced in successive versions.
