I’m impressed with the comprehensive knowledge of the instrument definition library, but a few things would be helpful:
- Brackets on bowings. This notation is used to show an optional bow change mid-slur.
- Extension and shift symbol support for fingerings: currently fingerings only support numbers, but extensions (x) and shift (-) notations are unsupported.
- More engraving support for built-in shift notation: There are not many ways to move these around or change their size, but many editions use different-looking lines that point from one fingering to the next.
- Special playing techniques: I am aware you can add these, but I find it odd that there are key clicks for winds but no chop/slap notations for strings.
Most of these notations have workarounds which involve loose lines and symbols, but fixed settings would be handy.
